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. Built from multiple layers of stainless steel\n  with outer layers embossed and coated in Viton, heat resistant to 482°F, for strength, corrosion\n  resistance, and a seal that holds through repeated heat cycles. Designed for aluminum head to aluminum\n  block applications and requires no additional sealant. The embossing design distributes clamp load\n  evenly across the sealing surface, so no re-torque is needed after installation. Bore and thickness are\n  specific to this engine's stock configuration, confirm your build matches before ordering if you've\n  milled the head or changed compression. One head gasket per order.\n\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003cspan class=\"tag\"\u003e2017-2021 Honda Civic Si\/Sport\/ (1.5T)\u003c\/span\u003e\u003cbr\u003e\u003cdiv\u003e\u003cspan class=\"tag\"\u003e2017-2021 Honda CR-V\u003c\/span\u003e\u003c\/div\u003e \n\u003c\/li\u003e\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\n\n\u003c\/li\u003e\n\n\n\n \n\u003cli id=\"Included\"\u003e\n(1) Head Gasket\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\u003cli id=\"InstallGuide\"\u003e\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n","brand":"Cometic Gasket","offers":[{"title":"Default Title","offer_id":45784043421730,"sku":"COG-C14019-024","price":107.24,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/OrUZAr9LDvgnWOM0_5j_029_spin_processed.png?v=1781537026","url":"https:\/\/www.hybrid-racing.com\/products\/cometic-mls-head-gasket-l15b7-735mm","provider":"Hybrid Racing","version":"1.0","type":"link"}
