Injen Evolution Cold Air Intake – BMW 228i / 328i / 428i (N20, F22 / F30 / F32)

OVERVIEW

The EVO1103 is Injen's Evolution sealed cold air intake for the N20-powered BMW. It was designed using current engineering tools and techniques, and the sealed housing encloses an Injen SuperNano-Web dry air filter for strong airflow and added performance. The kit ships with all the hardware needed for a straightforward installation.

The two-piece roto-molded housing carries the Injen Midnight Edition badge for a cleaner, more aggressive under-hood appearance, and the roto-molded intake tube is custom designed and dyno-tuned to produce power while retaining a clean, quality fit. The SuperNano-Web dry filter is built to increase flow while keeping servicing simple.

Hardware quality is consistent throughout, from the stainless steel band clamps with an inner protective liner to the reinforced automotive-grade silicone couplers. After design work and dyno testing, Injen rates the EVO1103 at up to 15 additional horsepower and 17 lb-ft of torque.
