The K&N 57 Series FIPK air intake for select 1988–1991 Honda Civic and CRX models replaces the factory air filter and housing to reduce restriction and smooth airflow. Its chrome-topped high-flow filter and engineered intake tube increase airflow to the throttle body, yielding a guaranteed increase in horsepower and torque. The washable, reusable filter can go up to 100,000 miles between services under normal driving, and the system typically installs in about 90 minutes using factory mounting points.
