More Power and Dramatic Sound Improvement

This plug and play air intake system unlocks up to 8whp to the wheels from your G20 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 S&B 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. Made in the USA.
