Cometic's 73.5mm, .024 inch MLS gasket is\n  built for exactly this engine, and it's the gasket most people land on when they're done trusting the\n  factory piece to keep up. It's made from multiple layers of stainless steel instead of the composite\n  material Honda uses, so it seals better, handles more heat, and doesn't get brittle and start leaking\n  the way a stock gasket can once you're running real boost.\n\u003c\/p\u003e\n\n\u003ch4\u003eHere's Why Your Stock Gasket Struggles Under Boost\u003c\/h4\u003e\n\u003cp\u003e\n  The factory gasket on the L15B7 is fine for stock power, but it's not built with much room to spare.\n  Add more boost, run it harder, or just put a lot of miles on a turbo motor, and that factory gasket can\n  start to fail. You'll see it as a coolant leak you can't find, white smoke out the tailpipe, coolant\n  mixing into the oil, or a car that overheats for no obvious reason. Once that happens, you're not just\n  buying a gasket, you're often looking at a warped head too. Swapping to an MLS gasket before that\n  happens, especially if you've already turned up the boost, is cheap insurance against a much bigger\n  repair down the road.\n\u003c\/p\u003e\n\n\u003ch4\u003eMultiple Layers Of Stainless Steel, Built To Take The Heat\u003c\/h4\u003e\n\u003cp\u003e\n  This gasket is built from several layers of stainless steel stacked together, which gives it the\n  strength and rebound a single-layer gasket can't match, plus real resistance to corrosion over time.\n  The outer layers are embossed and coated with Viton, a rubber coating that handles heat up to 482°F, so\n  it keeps sealing through hard heat cycles instead of hardening and losing its seal. Because it's MLS,\n  it's built for exactly what you've got under the hood, an aluminum head clamping down on an aluminum\n  block, and it handles the shearing forces between those two metals without any extra sealant. You don't\n  add anything, you just install it and it does its job.\n\u003c\/p\u003e\n\n\u003ch4\u003eNo Re-Torque, One Less Thing To Remember\u003c\/h4\u003e\n\u003cp\u003e\n  Cometic tunes the embossing pattern on this gasket so the clamp load spreads evenly across the whole\n  sealing surface the moment you torque it down. That means no coming back in a few hundred miles to\n  re-torque the head bolts like some gaskets call for, and less risk of warping the head from uneven\n  clamping. You torque it to spec once, and it's done. If you're already in there doing head work,\n  installing studs, or chasing a leak, that's one less step to track and one less thing that can go wrong\n  later.\n\u003c\/p\u003e\n\n\u003ch4\u003eGet The Right Thickness\u003c\/h4\u003e\n\u003cp\u003e\n  This is the 73.5mm bore, .024 inch thick version, and that thickness matters. It's built to match the\n  L15B7's stock bore and deck height, so it's the right call if you're replacing a blown stock gasket or\n  doing a head gasket job at stock compression. If you're milling the head, running a different piston\n  setup, or chasing a specific compression ratio, Cometic makes this gasket in other thicknesses too, so\n  make sure the one you order matches your actual build, not just your engine code. Order the wrong\n  thickness and it won't seal right no matter how well you torque it down.\n\u003c\/p\u003e\n\n\u003ch4\u003eFits The 2017-2021 Civic Si\u003c\/h4\u003e\n\u003cp\u003e\n  This gasket is built for the L15B7 in the 2017-2021 Honda Civic Si. If you're already pulling the head\n  for a gasket job on a turbo car, it's worth thinking about head studs at the same time, stock head\n  bolts stretch under higher boost, and studs give you more consistent clamping for the long haul. Pair\n  the two and you've got a head gasket setup that can handle a lot more than stock without worrying about\n  it again.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCometic MLS head gasket (C14019-024) for the Honda L15B7\u003c\/li\u003e\n  \u003cli\u003e73.5mm bore, .024 inch compressed thickness\u003c\/li\u003e\n  \u003cli\u003eMultiple layers of stainless steel for strength and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eViton coating on outer layers, heat resistant to 482°F\u003c\/li\u003e\n  \u003cli\u003eEven clamp load embossing, no re-torque needed after install\u003c\/li\u003e\n  \u003cli\u003eBuilt for aluminum head to aluminum block applications\u003c\/li\u003e\n  \u003cli\u003eNo additional sealant required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFits These Cars\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2017-2021 Honda Civic Si (L15B7)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  Note: Cometic MLS head gasket (part number C14019-024) for the Honda L15B7, 73.5mm bore, .024 inch\n  compressed thickness, for the 2017-2021 Honda Civic Si.

Don't let the head gasket be the thing that ends the build early. This is Cometic's 86.5mm,\n  .030 inch MLS gasket for the K20A2, K20A3, and K20Z1, and it's what a lot of builders reach for once\n  they've decided the factory gasket's days are numbered. It's stacked stainless steel instead of the\n  composite Honda uses, so it handles heat and pressure the stock gasket was never asked to deal with,\n  and you don't need a single drop of sealant to make it work.\n\u003c\/p\u003e\n\n\u003ch4\u003eHere's How Your Stock Gasket Tells You It's Done\u003c\/h4\u003e\n\u003cp\u003e\n  The factory gasket's fine if you're keeping things stock, but there's not much margin built in. Add\n  boost, push the compression, or just run a high-strung K20 hard for years, and that factory gasket\n  starts running out of room to work. You'll know it when you see it: a coolant leak you can't pin down,\n  white smoke out the back, coolant showing up in your oil, or the temp gauge creeping up for no reason\n  you can find. Once you're seeing that stuff, you're not just buying a gasket anymore, you're probably\n  looking at a warped head too. Get ahead of it with an MLS gasket now, especially if you've already\n  turned the engine up, and you're not gambling with a much bigger bill later.\n\u003c\/p\u003e\n\n\u003ch4\u003eStacked Stainless, Built To Hold The Line\u003c\/h4\u003e\n\u003cp\u003e\n  You're getting three layers of stainless steel here, stacked together for strength and rebound a\n  single-layer gasket just can't touch, plus corrosion resistance that holds up over time. The outer\n  layers are embossed and coated with Viton, a rubber coating rated to 482°F, so it keeps sealing\n  through hard heat cycles instead of cooking and giving up like older gasket materials do. Since it's\n  MLS, it's built for exactly what you've got, an aluminum head clamping onto an aluminum block, and it\n  shrugs off the shearing forces between those two metals without any extra sealant. Bolt it in and it\n  does its job, that's it.\n\u003c\/p\u003e\n\n\u003ch4\u003eNo Re-Torque, So You Can Forget About It\u003c\/h4\u003e\n\u003cp\u003e\n  Here's a small thing that saves you a real headache. Cometic tunes the embossing so the clamp load\n  spreads evenly across the whole sealing surface the second you torque it down. You're not coming back\n  in a few hundred miles to re-torque the head bolts like some gaskets make you do, and you're not\n  risking an uneven clamp warping the head either. Torque it once to spec and walk away. If you're\n  already deep into a head job, studs, or chasing down a leak, that's one less thing you've got to\n  remember six months from now.\n\u003c\/p\u003e\n\n\u003ch4\u003eMake Sure This Is Your Bore\u003c\/h4\u003e\n\u003cp\u003e\n  Real talk before you buy: 86.5mm isn't the K20's stock bore, it's a 0.5mm overbore. If your block's\n  been bored out to 86.5mm, this is your gasket. If you're still running the stock 86mm bore, you'll want\n  the 86mm version instead, not this one. The .030 inch thickness is built around stock deck height and\n  compression, so if you're milling the head or chasing a different compression ratio, Cometic makes this\n  in other thicknesses too. Match it to your actual block, not just your engine code, because the wrong\n  bore or thickness won't seal right no matter how perfectly you torque it down.\n\u003c\/p\u003e\n\n\u003ch4\u003eFits These Engines\u003c\/h4\u003e\n\u003cp\u003e\n  This gasket's built for the K20A2, K20A3, and K20Z1, which covers the 2002-2006 Acura RSX Base,\n  2002-2006 Acura RSX Type S, and 2002-2005 Honda Civic Si. While you've got the head off, it's worth\n  thinking about head studs too. Stock head bolts stretch once you're making real power, and studs keep\n  your clamping consistent for the long haul. Do both at once and you've built yourself a gasket setup\n  that can take a lot more than stock without you having to think about it again.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCometic MLS head gasket (C14079-030) for the K20A2, K20A3, and K20Z1\u003c\/li\u003e\n  \u003cli\u003e86.5mm bore, .030 inch compressed thickness, for a 0.5mm overbore\u003c\/li\u003e\n  \u003cli\u003e3 layers of stainless steel for strength and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eViton coating on outer layers, heat resistant to 482°F\u003c\/li\u003e\n  \u003cli\u003eEven clamp load embossing, no re-torque needed after install\u003c\/li\u003e\n  \u003cli\u003eBuilt for aluminum head to aluminum block applications\u003c\/li\u003e\n  \u003cli\u003eNo additional sealant required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFits These Cars\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2002-2006 Acura RSX Base (K20A3)\u003c\/li\u003e\n  \u003cli\u003e2002-2006 Acura RSX Type S (K20A2\/K20Z1)\u003c\/li\u003e\n  \u003cli\u003e2002-2005 Honda Civic Si (K20A3)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  Note: Cometic MLS head gasket (part number C14079-030) for the K20A2, K20A3, and K20Z1, 86.5mm bore,\n  .030 inch compressed thickness, for the 2002-2006 Acura RSX Base, 2002-2006 Acura RSX Type S, and\n  2002-2005 Honda Civic Si.

Milled the head, or running a different piston combo that\n  changes your compression? You'll want a thicker option to bring things back in line, that's exactly\n  what the .040 and .051 are there for. The 87.5mm bore itself covers stock-bore K24s and a common K20\n  overbore size, so make sure 87.5mm actually matches your block before you order, and pick the thickness\n  that matches your build, not just your engine code.\n\u003c\/p\u003e\n\n\u003ch4\u003eFits These Engines\u003c\/h4\u003e\n\u003cp\u003e\n  This gasket is built for the K20A2, K20A3, K20Z1, and K24A1, covering the 2002-2006 Acura RSX Base and\n  Type S, the 2002-2005 Honda Civic Si, and the 2002-2006 Honda CR-V. If you're already pulling the head,\n  it's worth thinking about head studs too. Stock head bolts stretch once you're making real power, and\n  studs keep your clamping consistent for the long haul. Do both at once and you've got a gasket setup\n  that can take a lot more than stock without a second thought.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCometic MLS head gasket for the K20A2, K20A3, K20Z1, and K24A1\u003c\/li\u003e\n  \u003cli\u003e87.5mm bore, available in .030 (C14039-030), .040 (C14039-040), and .051 (C14039-051) inch thickness\u003c\/li\u003e\n  \u003cli\u003e3 layers of stainless steel for strength and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eViton coating on outer layers, heat resistant to 482°F\u003c\/li\u003e\n  \u003cli\u003eEven clamp load embossing, no re-torque needed after install\u003c\/li\u003e\n  \u003cli\u003eBuilt for aluminum head to aluminum or cast iron block applications\u003c\/li\u003e\n  \u003cli\u003eWorks for naturally aspirated and boosted K-series builds\u003c\/li\u003e\n  \u003cli\u003eNo additional sealant required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFits These Cars\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2002-2006 Acura RSX Base (K20A3)\u003c\/li\u003e\n  \u003cli\u003e2002-2006 Acura RSX Type S (K20A2\/K20Z1)\u003c\/li\u003e\n  \u003cli\u003e2002-2005 Honda Civic Si (K20A3)\u003c\/li\u003e\n  \u003cli\u003e2002-2006 Honda CR-V (K24A1)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  Note: Cometic MLS head gasket for the K20A2, K20A3, K20Z1, and K24A1, 87.5mm bore, available in .030\n  (C14039-030), .040 (C14039-040), and .051 (C14039-051) inch compressed thickness, for the 2002-2006\n  Acura RSX Base and Type S, 2002-2005 Honda Civic Si, and 2002-2006 Honda CR-V.

The factory head gasket on these\n  engines wasn't built with a lot of margin, and once you're on boost or spinning it past where Honda\n  intended, that factory gasket is one of the first things to give up on you. This is Cometic's 75.5mm,\n  .030 inch MLS gasket for the D16Z6, D16Y7, and D16Y8, and it's three layers of stainless steel where\n  your factory composite used to be. It's a gasket that's actually built for what you're asking the\n  engine to do.\n\u003c\/p\u003e\n\n\u003ch4\u003eHere's How You Know Your Factory Gasket's Done\u003c\/h4\u003e\n\u003cp\u003e\n  The signs aren't subtle once they show up. You'll see white smoke from the exhaust, coolant mixing into\n  the oil, a coolant leak you can't track down, or a temperature gauge that climbs for no obvious reason.\n  Any one of those means the head gasket's gone, and by the time you're seeing them, there's a real chance\n  the head's warped too. Replacing a blown gasket is one thing; replacing a gasket and a warped head is a\n  completely different bill. Get the MLS gasket in before that happens, especially if you've already\n  added boost or turned the engine up, and you don't have to find out the hard way.\n\u003c\/p\u003e\n\n\u003ch4\u003eThree Layers Of Stainless, Viton Coated And Built To Stay Sealed\u003c\/h4\u003e\n\u003cp\u003e\n  Here's what you're actually getting. Three layers of stainless steel, outer layers embossed and coated\n  with Viton rated to 482°F, and an uncoated stainless center shim in the middle. The Viton coating keeps\n  the outer layers from degrading around oil and coolant, and the embossing is what locks the seal in\n  place without any sealant. You don't add anything, you just install it and it does the job. The D-series\n  is an aluminum head on a cast iron block, which creates shearing forces between the two materials as\n  they heat and cool at different rates. MLS construction handles that, where a composite gasket\n  eventually can't.\n\u003c\/p\u003e\n\n\u003ch4\u003eNo Re-Torque, So You're Done When You're Done\u003c\/h4\u003e\n\u003cp\u003e\n  Once you torque the head bolts to spec, you're finished. The embossing design spreads the clamp load\n  evenly across the whole sealing surface, so you're not coming back a few hundred miles later to\n  re-torque the head bolts and risk uneven clamping. It's one of those small things that matters a lot\n  when you're in the middle of a build and you've already got enough to keep track of.\n\u003c\/p\u003e\n\n\u003ch4\u003e75.5mm Is A Common D16 Overbore, So Make Sure It's Yours\u003c\/h4\u003e\n\u003cp\u003e\n  The stock D16 bore is 75mm, so this 75.5mm gasket is built for a block that's been bored 0.5mm over.\n  If your block is still at stock bore, you'd want the 75mm version instead, not this one. And if you've\n  milled the head or you're chasing a specific compression ratio, Cometic makes this gasket in .040 and\n  .051 inch thicknesses too, so you can match the thickness to your actual deck height instead of just\n  going with the default. Match the bore and thickness to your build before you order, and you're set.\n  If you're already in here pulling the head, now's the time to swap in ARP head studs too. Stock head\n  bolts stretch under boost, and studs keep your clamping consistent so you're not back in here again\n  sooner than you planned.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCometic MLS head gasket (C4251-030) for the D16Z6, D16Y7, and D16Y8\u003c\/li\u003e\n  \u003cli\u003e75.5mm bore, .030 inch compressed thickness\u003c\/li\u003e\n  \u003cli\u003e3 layers of stainless steel for strength and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eViton coating on outer layers, heat resistant to 482°F\u003c\/li\u003e\n  \u003cli\u003eEven clamp load embossing, no re-torque needed after install\u003c\/li\u003e\n  \u003cli\u003eBuilt for aluminum head to cast iron block applications\u003c\/li\u003e\n  \u003cli\u003eNo additional sealant required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFits These Cars\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1992-1995 Honda Civic EX\/Si (D16Z6)\u003c\/li\u003e\n  \u003cli\u003e1993-1995 Honda Del Sol Si (D16Z6)\u003c\/li\u003e\n  \u003cli\u003e1996-2000 Honda Civic CX\/DX\/LX (D16Y7)\u003c\/li\u003e\n  \u003cli\u003e1996-2000 Honda Civic EX (D16Y8)\u003c\/li\u003e\n  \u003cli\u003e1996-1997 Honda Del Sol S (D16Y7)\u003c\/li\u003e\n  \u003cli\u003e1996-1997 Honda Del Sol Si (D16Y8)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  Note: Cometic MLS head gasket (part number C4251-030) for the Honda D16Z6, D16Y7, and D16Y8, 75.5mm\n  bore, .030 inch compressed thickness.
