The Injen IS short‑ram intake for 1988–1991 Honda Civic and CRX Si is a bolt‑on underhood upgrade that improves airflow and delivers measurable power gains while preserving safe air‑fuel ratios. Its mandrel‑bent aluminum tubing provides a smooth path for air and the system is available in polished or black finishes. The kit includes a fully serviceable Injen SuperNano‑Web dry air filter, vacuum hoses and hardware, produces a more aggressive intake tone, and is backed by Injen’s limited lifetime warranty.
