K&N 57-0366 Induction Kit - BMW E36, E46 and Z3 2.0 Straight Six

Give your BMW a sharper, freer-breathing intake with the K&N 57-0366 induction kit. This uprated intake replaces the restrictive factory airbox with a high-flow, serviceable filter and model-specific pipework to let your straight six breathe properly.

We run this setup on our own cars and our customers consistently report a noticeable improvement in driveability and sound.

If you are searching for an intake upgrade for your BMW six cylinder, this kit is a proven choice for daily road use and enthusiast builds alike. No ECU tune required, just bolt on and enjoy.
