aFe Magnum FLOW Pro DRY S Air Filter - 2020-23 BMW X3/X4 M40i (G01/G02) B58

A drop-in performance panel filter that takes the place of the paper element in the factory airbox. It's the simplest intake change you can make on an X3 or X4 M40i: no new tubing, no new box, just a freer-flowing filter you can clean and reuse instead of replacing.

What you get

• Three-layer synthetic dry media. No oil is used, so there's nothing to over-oil or get onto sensors, and aFe rates it for street use.
• Rounded, deep pleats spaced evenly for more usable filter area, more flow and more room to hold dirt.
• Full polyurethane frame that holds its molded shape through repeated heat cycles in the engine bay.
• Flexible bump seal around the edge that conforms to the airbox, so no gasket or sealant is needed.
• Washable and reusable. It is cleaned with aFe's dry-filter cleaner.

Good to know

• aFe states this filter does not need a CARB EO number.
