BMW Z3 E36-7 1999 to 2003 Sports Cotton Intake Filter Upgrade

Give your Z3 a proper breath of fresh air. This premium K&N cotton gauze filter element is a direct-fit insert for the standard air box, engineered to improve engine breathing for sharper throttle response and a more eager revving feel. It is serviceable and built to last, so you can clean and re-oil it rather than buying disposable paper filters again and again.

We run this filter on customer BMW Z3s in our workshop and the feedback has been excellent. Owners consistently report crisper response, smoother intake flow and a subtle induction note, all while retaining factory refinement. No software changes needed and no cutting required. Simply swap it in and drive.

Why this upgrade works

• Free-flowing oiled cotton media promotes better breathing for responsive acceleration
