8th Gen Civic Si Skunk2 Cold-Air Intake

Fits 8th Gen Honda Civic Si

Skunk2’s Cold-Air Intake is manufactured from molded polymer plastic for superior intake air insulation, when compared to aluminum, as well as for a smooth, continuous taper. When compared to aluminum, the thicker polymer material results in a superior thermal barrier and lower intake air temperatures.

Each kit includes:

• A 3.5-inch internal diameter lower tube 
• A tapered 3.5-inch to 3.0-inch internal diameter upper tube that connects to the factory throttle body with a high-quality, silicone connector (larger diameter connector for use with Skunk2 throttle bodies or similar sold separately).
• Relocation hardware for the battery
• ECU
• Fuse box
• Cooling system reservoir tank
• High-quality stainless steel clamps and mounting hardware

The two-piece design and supplied MAF sensor adapter allows for compatibility with vehicles utilizing the factory ECU. A silicone coupler featuring a smooth, tapered transition between the two tubes is also included for vehicles equipped with aftermarket engine management systems that don’t utilize MAF sensors.

In an effort to reduce the possibility of submerging the air filter during wet conditions, Skunk2’s design positions the air filter downward-facing for approximately two inches of additional ground clearance when compared to competitors’ designs that locate the air filter from the side. That, combined with a design that doesn’t require cutting or modifying the factory fender liners, greatly reduces the chances of water entering the intake during wet conditions.

Unlike other intake systems, only Skunk2’s unique design and brackets allow for the OEM battery to be retained. A specially shaped silicone upper radiator hose is also included with each kit to ensure maximum clearance for the intake tubing and proper fitment.
