Product Description

The K&N AirCharger Performance Air Intake System replaces the Civic's restrictive factory air filter and air intake housing, delivering up to 50% more airflow than the stock setup while smoothing and straightening intake air for real, usable power throughout the RPM range. Dyno-tested and no ECU tune required, this system also sharpens throttle response and improves acceleration when towing or climbing grades.

The system pairs a free-flowing HDPE intake tube with an oversized, black rubber-topped K&N High-Flow cone filter, protected by a custom heat shield that installs into the original air box space. The intake tube accommodates the factory mass air sensor and crankcase vent hose, and the whole system typically installs in 90 minutes or less using the vehicle's existing factory mounting points.

Backed by K&N's 1,000,000 Mile/10 Year Limited Warranty, with a washable, reusable filter good for up to 100,000 miles between services. Note: not legal for sale or use in California or other CARB-adopting states, and will not fit the Civic Type R.
