Product Description

Injen's Evolution Cold Air Intake brings genuine dyno-proven performance to the 10th-gen Civic Si, delivering gains of up to 22 horsepower and 18 lb-ft of torque while working with the stock ECU calibration -- no tune required. The one-piece sealed housing uses Injen's patent-pending Twist-Lock system to securely fasten the SuperNano-Web dry air filter, eliminating unnecessary parts for one of the simplest installations available.

A roto-molded, dyno-tuned intake tube retains an OE-quality fit while Injen's patented tuning process funnels air past the MAF sensor at a precise rate, ensuring accurate fuel trims and aggressive power gains without check engine light concerns. Quality hardware throughout -- stainless steel band clamps with an inner protective liner and reinforced automotive-grade silicone couplers -- ensures a secure, reliable fit.

Made in Pomona, California, and backed by Injen's Limited Lifetime Warranty. Note: not currently CARB exempt -- cannot be shipped to California or several other CARB-adopting states. Replacement filter is part X-1110-BB.
