Injen IS Performance Polished Short Ram Intake for 1988-1991 Honda Civic/CRX (L4-1.5L) IS1501P

The Injen Technology IS Performance Short Ram Air Intake (IS1501P) is a direct-fit performance upgrade for 1988-1991 Honda Civic EX, Si, and RT 4WD models, as well as the CRX Si (L4-1.5L). This kit replaces the restrictive factory air box with a mandrel-bent T6-6061 aluminum intake tube, designed to provide a smooth, uninterrupted path for highly efficient airflow. The result is improved throttle response, increased horsepower, and an aggressive, throaty engine tone under load.

The heart of this intake system is the fully serviceable Injen SuperNano-Web dry air filter. This media provides a larger surface area for increased airflow while maintaining superior filtration standards without the need for filter oil. Engineered for reliability, this system maintains safe air/fuel (A/F) ratios throughout the powerband, ensuring consistent performance without requiring additional ECU tuning.
