The Injen RD Series cold air intake for selected 1999–2001 BMW 323i/328i and 2001 325i models replaces restrictive stock plumbing with mandrel-bent 6061-T6 aluminum tubing and a serviceable SuperNano-Web dry filter to improve mid-range power and throttle response. The system aims to preserve safe air/fuel ratios, provides an aggressive induction tone, and is available polished or black with a limited lifetime warranty.
