Injen RD Series Race Division Intake Systems

5.0 out of 5 stars 2 Customer Reviews

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