Cams are how you\n  do it, and these Skunk2 Ultra Series Stage 2 camshafts are one of the biggest naturally aspirated gains you\n  can bolt into your Civic Si or ILX. The K24Z7 is an underrated motor that responds hard to a good set of\n  cams, and Skunk2 built these to unlock it. But there's one requirement you absolutely have to read before\n  you buy, so don't skip ahead.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat Cams Actually Do To Your Powerband\u003c\/h4\u003e\n\u003cp\u003e\n  Here's what's happening when you throw a set of cams in. These Stage 2 cams open your valves higher (more\n  lift) and hold them open longer (more duration), which lets the engine breathe way better up top where it\n  counts. The payoff is a big jump in peak power, but here's the honest part you need to understand: it moves\n  your powerband up, Skunk2 says peak power shifts about 1500 rpm higher. So you're trading a little bit of the\n  low-end for a whole lot of top-end. Translation, this cam wants to be revved. If you love winding the K24\n  out to redline, you're going to fall in love with how it pulls up high.\n\u003c\/p\u003e\n\n\u003ch4\u003eThe Power On Tap\u003c\/h4\u003e\n\u003cp\u003e\n  These aren't a couple-horsepower gimmick. On a naturally aspirated build, Skunk2 sees typical gains of\n  25-50 horsepower from these cams, and on a forced-induction setup, over 75 horsepower. That's a serious\n  swing for a valvetrain part. Just keep it real with your expectations: those numbers depend on your engine's\n  condition, your supporting mods, and your tune. Cams are a piece of a package, not a magic bolt-on, dial the\n  whole combo in and they deliver.\n\u003c\/p\u003e\n\n\u003ch4\u003eNon-Negotiable: You Need Upgraded Valve Springs\u003c\/h4\u003e\n\u003cp\u003e\n  Read this twice, because it's the one that'll bite you. These are high-lift cams, and your stock valve\n  springs cannot handle the extra lift, period. Run these on factory springs and you're asking for valve float\n  and real engine damage, which is a catastrophically expensive way to save a few bucks. So high-lift capable\n  performance valve springs aren't optional here, they're required. Budget for a proper set of springs (and\n  retainers if your setup calls for it) as part of this install, and do it right the first time.\n\u003c\/p\u003e\n\n\u003ch4\u003ePlan On A Tune\u003c\/h4\u003e\n\u003cp\u003e\n  One more thing to line up: cams need a tune to actually make their power and run clean. To get the gains\n  Skunk2 is talking about and keep the car running right with that shifted powerband, you'll want it tuned on\n  something like a Hondata FlashPro. Factor the tune into your plan alongside the cams and springs, and the\n  whole package comes together.\n\u003c\/p\u003e\n\n\u003ch4\u003eBuilt By Skunk2, The Right Way\u003c\/h4\u003e\n\u003cp\u003e\n  Skunk2 doesn't cut corners on these. The cams are machined from forged 8660 alloy steel blanks, induction\n  hardened, and CNC precision ground, so they're built to live under a hard-revving motor. The lobe profiles\n  are designed in-house using simulation and CAD modeling and then validated on the dyno, so the power gains\n  aren't guesswork, they're proven. Skunk2's been a leader in Honda valvetrain for a long time, and this is the\n  kind of part that reputation is built on.\n\u003c\/p\u003e\n\n\u003ch4\u003eFor Off-Road And Racing Use\u003c\/h4\u003e\n\u003cp\u003e\n  Heads-up on the legal side: these camshafts are not CARB approved and are intended for off-road and racing\n  use only. They require CARB acknowledgment at checkout. So this is a part for a track or race build, not\n  something that'll pass emissions, plan accordingly for where and how you run the car.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSkunk2 Ultra Series Stage 2 camshafts for the K24Z7 (part number 305-05-9700)\u003c\/li\u003e\n  \u003cli\u003eHigh-lift, increased-duration profile for big top-end power\u003c\/li\u003e\n  \u003cli\u003eTypical gains of 25-50 hp naturally aspirated, 75+ hp forced induction (with proper supporting mods and tuning)\u003c\/li\u003e\n  \u003cli\u003eForged 8660 alloy steel, induction hardened, CNC precision ground\u003c\/li\u003e\n  \u003cli\u003eIn-house CAD-designed, dyno-validated lobe profiles\u003c\/li\u003e\n  \u003cli\u003eHigh-lift capable performance valve springs required (not included)\u003c\/li\u003e\n  \u003cli\u003eTune required to realize gains\u003c\/li\u003e\n  \u003cli\u003eNot CARB approved, for off-road and racing use only\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFits These Cars\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2012-2015 Honda Civic Si (K24Z7)\u003c\/li\u003e\n  \u003cli\u003e2013-2015 Acura ILX (2.4L, K24Z7)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  Note: Skunk2 Ultra Series Stage 2 camshafts for the K24Z7 engine, part number 305-05-9700, fitting the\n  2012-2015 Honda Civic Si and 2013-2015 Acura ILX (2.4L). These are high-lift, increased-duration camshafts\n  that shift peak power roughly 1500 rpm higher and typically produce gains of 25-50 hp on naturally aspirated\n  engines and over 75 hp on forced-induction engines; actual results vary with engine condition, supporting\n  parts, and tuning. High-lift capable performance valve springs are required to run these cams safely and are\n  not included; running stock valve springs risks valve float and engine damage. A tune is required to realize\n  the gains. The camshafts are machined from forged 8660 alloy steel blanks, induction hardened, and CNC\n  precision ground, with in-house CAD-designed, dyno-validated lobe profiles. These camshafts are not CARB\n  approved and are intended for off-road and racing use only, requiring CARB acknowledgment at purchase. One\n  camshaft set per order.\n\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n 2013-2015 Acura ILX\u003cdiv\u003e2012-2015 Honda Civic Si\u003c\/div\u003e \n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\u003c\/ul\u003e\n","brand":"Skunk2 Racing","offers":[{"title":"Default Title","offer_id":45998884487202,"sku":"SK2-305-05-9700","price":1092.45,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/SK2-305-05-9700_bjnk.jpg?v=1783975119","url":"https:\/\/www.hybrid-racing.com\/products\/skunk2-ultra-stage-2-camshafts-12-15-civic-si","provider":"Hybrid Racing","version":"1.0","type":"link"}
