Skunk2 Composite Cold Air Intake for 12-15 Civic Si

Skunk2 Composite Cold Air Intake for 12-15 Civic Si

Unlock cooler air, sharper throttle response, and a throatier VTEC growl with the Skunk2 Composite Cold Air Intake for 12-15 Civic Si. Skunk2 Racing molded this system from a heat-soaking-proof composite polymer rather than aluminum, keeping incoming air up to 40 °F cooler on hot, stop-and-go drives. Cooler, denser air means stronger mid-range torque and a noticeable surge all the way to the 7,000-rpm redline.

Why you’ll feel the difference

• Big-flow architecture – A 3.5-in. internal-diameter lower tube feeds a tapered upper runner for turbulence-free velocity straight into the factory throttle body.
• Championship-bred design – Developed side by side with Compass360 race cars, then re-tuned for daily-driver manners.
• Built-in heat shielding – Thick-wall composite resists engine-bay temperatures that quickly heat-soak metal intakes.
• Safer in the rain – The filter mounts low and toward the engine bay’s center, adding ground clearance and drastically lowering the chance of water ingestion.
• No compromises – Retains your OEM battery, OEM fender liners, and all factory sensors; no hacking, drilling, or CEL worries.

Expect crisper acceleration, a satisfying induction note, and reliability that lasts longer than thin-wall aluminum tubes—backed by Skunk2’s reputation for Honda performance.
