BMS Billet Intake for Gen 2 B58 G20 G21 M340i and G42 M240iX

More Air = More Power and Dramatic Sound Improvement!

The Burger Motorsports billet B58 air intake system unlocks up to 8+whp to the wheels from your G20 Gen 2 B58 M340i or M340iX 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 a clean look, and includes a reusable BMS high flow inverted cone filter. The OEM cold air intake tube, airbox bottom, and factory heat shield remain fully functional for ducting and heat isolation. Install takes only minutes and is fully reversible. Filters are available in red or blue. Made in the USA.
