The RD series is a cold air intake system for the enthusiast craving mid-range power. The intake tube is strategically placed behind the front bumper to acquire colder, denser air. Although most of the RD series is a one-piece design, several are two-piece designs due to the mass air flow meters. Every RD system is certified or pending by the California Air Resource Board and backed by Injen Technology's limited lifetime warranty.

About Manufacturer: Injen

Injen Technology

Injen Technology has made it a point to stay at the forefront of performance technology making only the best air intake one can envision. In 1999 Injen was faced with such a strong demand in both US and Canada that in order to meet production schedules it became essential to branch out and add a second building.

In 2003, Injen Technology launched our Super SES stainless steel cat-back exhaust systems complimenting our line of air intake systems. Each exhaust system was equipped with the Injen signature style slanted mufflers and featured highly polished stainless steel.
