The Injen RD cold air intake for 2003–2004 Mazdaspeed Protege 2.0L turbo is a bolt-on system built around mandrel-bent 6061-T6 aluminum tubing and a serviceable SuperNano-Web dry filter. The intake draws cooler air from behind the bumper, preserves safe air–fuel ratios, and delivers an aggressive intake tone. Dyno-proven gains and an Injen limited lifetime warranty complete the package.
