The Injen RD Series cold air intake for 2003–2004 Toyota Corolla 1.8L replaces the factory intake with mandrel‑bent 6061‑T6 aluminum tubing and a serviceable SuperNano‑Web dry filter to improve mid‑range power and throttle response while maintaining safe air‑fuel ratios. The system yields a more aggressive induction tone, is available in black or polished finishes, and is backed by Injen's limited lifetime warranty.
