Injen Evolution Cold Air Intake – BMW 230i / 330i / 430i (B46)

OVERVIEW

The EVO1104 Evolution cold air intake brings the B46/B48-powered BMW 2, 3 and 4 Series up a level. Injen designed the kit with current engineering tools and techniques, starting with a one-piece sealed roto-molded housing that uses the patent-pending Twist-Lock system to secure a large SuperNano-Web dry air filter, and carrying premium hardware throughout.

The roto-molded intake tube is custom designed and dyno-tuned to produce power while retaining an OE-quality fit, and the housing carries Injen's Clear-View badge so filter condition can be checked without disassembly. Stainless steel band clamps with an inner protective liner and a reinforced automotive-grade silicone coupler give a secure fit, and the low part count makes this one of the quicker intake installations on the market.

Injen's dyno testing shows the EVO1104 producing up to 7 additional horsepower and 7 lb-ft of torque, and the kit is designed to run on the stock calibration. It carries the Injen Technology Limited Lifetime Warranty.
