Cold Air Intake for 2012-2015 Honda Civic Si / Acura ILX 2.4L

🏁 Your K24. Finally Breathing. The 9th-gen Civic Si and the Acura ILX 2.4L share the same K24Z7 — Honda's most refined naturally aspirated four-cylinder of the era. 201 horsepower, a rev limit past 7,000 RPM, and Honda's legendary i-VTEC engagement. But the factory airbox? It's throttling your K24 at the exact moment it wants to breathe hardest: top-end VTEC pull. Flashark's cold air intake opens it up: → 76mm smooth-bore aluminum tubing — matched to the K24Z7 throttle body → Dry high-flow filter — more surface area, zero oiling maintenance → Intake air 15-20°F cooler vs. stock → VTEC engages harder and sounds better → No check engine light — no tune needed → Bolt-on in 90 minutes The K24Z7 was built for this upgrade. BEFORE YOU BUY — READ THIS • Stock ECU / No tune: ✅ Fully compatible (MAF housing calibrated for K24Z7) • With bolt-ons (header, exhaust, cam gears): ✅ Gains stack across all mods • Acura ILX 2.4L owners: ✅ Fits your car (same K24Z7 engine and intake manifold) • CARB compliance: Check product listing for CARB EO# before ordering if in CA, NY, or other CARB-regulated states. Why Flashark? 5 Reasons 1️⃣ K24Z7 OPTIMIZED — NO CEL The K24Z7 uses the same Honda MAF calibration family as the K20 series. Flashark's 76mm MAF housing is precision- machined to the exact bore your factory ECU expects. → No check engine light → No tune needed → VTEC engagement stays factory-smooth → i-VTEC map reads correctly at all RPMs 2️⃣ DRY FILTER — NO OILING HASSLE Skip the re-oiling ritual. Flashark's dry media filter: • Wash and reuse — no re-oiling ever • Better fine-particle filtration • Zero risk of coating the MAF with oil • Maintains airflow even when slightly dirty • One filter = the life of your Civic/ILX Maintenance: rinse every 15,000-20,000 mi, let dry fully, reinstall. 3️⃣ 76mm TUBING — RIGHT-SIZED FOR K24 The K24Z7's throttle body and intake manifold are matched to a 76mm bore. Flashark's mandrel-bent aluminum tubing: • Matches the K24Z7 throttle body exactly • Smooth-bore throughout — no turbulence • No reducer fittings that kill flow • Rapid heat dissipation vs. plastic factory box 4️⃣ COLD AIR — FROM THE FENDER WELL Position matters more than people think. Flashark's heat shield routes the intake to pull cool air from the front fender well area — the coldest zone in the engine bay on any Honda FB platform. Denser, cooler air = more power. Especially on a naturally aspirated K24 that depends entirely on air density. 5️⃣ BOLT-ON IN 90 MINUTES Designed specifically for the FB6 Civic Si and the Acura ILX 2.4L. Every bracket, mount, and clamp is an OEM-style replacement. Tools needed: Basic hand tools (ratchet, 10mm/12mm sockets) Estimated time: 60-90 minutes
