aFe stage 1 Magnum Force cold air intake kit for Z4 2.5i. This kit uses the aFe Pro Dry S synthetic cone filter with a heat shield that is ready to take the place of the stock airbox.

  • 4hp gain
  • 5ft-lbs gain
  • Improved engine sound
  • Synthetic oil-free filter
  • Easy install
The filter size and shape have been custom-designed just for these models to maximize the available surface area and permit more air into the engine. The synthetic filter material is denser than the aFe Pro 5R so it does not require any dust-retention oil, yet it flows up to 66% more air than a conventional stock paper filter. The Pro Dry S gives you a modest power increase with excellent filtration (99.2% efficiency) but less maintenance than the oiled filter. The Pro Dry S is cleaned using an aFe service kit and regular tap water.

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.
