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.
