aFe stage 1 Magnum Force cold air intake kit for Z4 3.0i (M54). This kit uses the aFe Pro 5R oiled cotton gauze cone filter with a heat shield that is ready to take the place of the stock airbox.

- Improved engine sound
- Free-flowing filter with dust-retention oil
- Easy install
The filter size and shape have been custom-deisgned just for these models to maximize the available surface area and permit more air into the engine. The stage 1 kits packs all of the filter technology of more expensive kits but in a more basic and straight-forward (budget friendly) package. Without a top cover the exposed air filter will drastically change the intake sound (for the better!) even with the heat shield. The Pro 5R is an oiled-cotton gauze filter media - the 5-layer filter flows a lot better than a paper filter while a small coating of retention oil traps dirt, dust, and debris. The Pro 5R filter is washable and reusable and only needs occassional clearning and re-oiling from an aFe service kit.
This intake, when installed on some of the models listed below, is approved for use in California under an Executive Order (EO, waiver). CARB EO# D-550-38.
