Injen Polished Cold Air Intake - E46 323, 325, 328

This is a short ram intake and filter kit that will go in place of the restrictive and unattractive factory airbox. Feel a dramatic boost to throttle response and build boost faster by eliminating restrictions and widening the intake track. The Injen 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 Injen RD series are a one-piece design several are two-piece designs due to the mass air flow meters. Every Injen RD system is certified or pending by the California Air Resource Board and backed by Injen Technology's limited lifetime warranty.

In 1999 Injen designed the first urethane filter with a built-in velocity stack for added performance. The Injen Technology Research and Development Team calculates each filters mesh and pleat count for each specific application during the development stages. Today the state-of-the-art Ea nano-fiber Injen/AMSOIL performance dry filter provides reliable performance and requires NO OIL. Both Injen Air Filters allow cleaning and durability for 1000's of miles to come.
