BMS B58 Billet Intake for F chassis BMW 140i/ 240i/ 340i/ 440i

More Power, More air, and Dramatic Sound Improvement

This plug & play air intake system unlocks up to 8whp to the wheels from your F chassis B58 BMW engine. In addition to the extra power throttle response, turbo spool, and sound are dramatically improved, finally allowing you to hear your turbo spool up under heavy acceleration. The system is CNC machined from billet aluminum, anodized black for strength and a clean look.  Includes a reusable BMS high flow inverted cone filter. The OEM cold air intake tube and insulating base remain fully functional. Install takes only minutes and is fully reversible. Made in the USA.

Add the optional silicone intake pipe for smoother airflow, better looks, and even better sound.

Installation of the F chassis B58 billet intake allows room for the B58 BMS Oil Catch Can.
 
Please note that the BMS B46/B48/B58 intakes are all different intakes and are not interchangeable.

Our intake retains everything that is good about the OEM intake system including the cold air ducting and light weight heat shielding airbox bottom; but, completely replaces the restrictive top end of the OEM intake with new high flow ducting and an inverted cone performance air filter to match.
