Skunk2 Composite Cold Air Intake for 06-11 Honda Civic Si
Unlock championship-proven horsepower, throttle response, and intake roar with the Skunk2 Composite Cold Air Intake for 06-11 Honda Civic Si. Born from Skunk2 Racing’s partnership with Compass360’s winning FA5/FG2 cars, this intake is engineered to do more than simply move air—it keeps it cool, dense, and ready to make power.
Why composite beats metal
- Heat-blocking polymer construction: 30% cooler inlet temps than aluminum designs, eliminating heat-soak during stop-and-go driving.
- Feather-light strength: drops unnecessary weight from the nose for sharper turn-in.
Built for real-world performance
- 3.5-in. constant-diameter lower tube: feeds your K20Z3 the airflow it craves, while the tapered upper tube maintains OEM throttle-body geometry for a turbulence-free charge.
- Two-piece design: tucks the high-flow filter low and forward yet sits a full 2 inches higher than typical CAIs—so you get cold air without the hydro-lock anxiety.
- Modular MAF boss: lets you swap between factory ECU management or speed-density tuning in minutes.
Complete, no-compromise kit
- Includes battery, ECU, fuse box, and coolant-tank relocation brackets—retain the stock battery and skip the parts-store scavenger hunt.
- Custom-molded upper radiator hose and premium 4-ply silicone couplers guarantee perfect clearance and leak-free clamping.
- All hardware is stainless steel; nothing to rust, ever.
Sound & gains you can feel
Expect a deeper, VTEC-charged induction note and dyno-verified gains of up to 8–12 whp on an untuned setup—more with complementary mods. Matched with Skunk2 headers, exhaust, or throttle body, the intake unlocks the breathing capacity Honda left on the table.
Vehicle fitment
2006-2011 Civic Si Coupe (FG2) and Sedan (FA5). Will not fit base model R18 engines.
Installation Snapshot
Intermediate | 2-3 hrs | Brackets, couplers, filter, clamps included | No tune or cutting required (ECU recalibration recommended for maximum gains).
