Easily delete the bulky factory intake muffler (resonator) for better sound and cleaner looks under the hood. The BMS intake muffler deletes are CNC machined from a solid block of lightweight billet aluminum and are available in anodized black, blue, or red.
This also allows you to make room for the BMS G20 BMW M340i oil catch can or the Toyota Supra Oil Catch Can.
Installation: Remove the factory intake muffler by unscrewing the two T20 Torx screws, lightly lubricate the inside of the cap and the rubber o-ring on the intake airbox lid, and twist the BMS unit on.
Made in the USA.
