More Air = More Power and Dramatic Sound Improvement

This plug and play air intake system unlocks up to 8whp to the wheels from your B46/B48 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 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.

Please note that the BMS B46/B48/B58 intakes are all different intakes and are not interchangeable.

Installation of the BMS B46/B48 billet intake allows room for the B48 BMS Oil Catch Can.
