The Injen RD cold air intake for 1988–1991 Honda Civic EX/SI and CRX Si (1.6L) delivers mid‑range power and a more aggressive intake note while refining engine bay looks. Mandrel‑bent 6061‑T6 aluminum tubing creates an uninterrupted airflow path to draw cooler air, and the SuperNano‑Web dry filter increases filter area for improved flow and filtration without upsetting A/F ratios. Available polished or black, the kit includes Injen’s limited lifetime warranty and CARB EO D-476-3.
