Triple-layer foam technology

Pipercross utilises a three-stage reticulated foam structure that captures particles progressively through the depth of the media. A coarse outer layer stops larger debris, a mid-density layer handles the bulk of contaminants and an inner fine layer protects the engine from the smallest particulates. The result is superior dirt-holding capacity and consistent, high-volume flow to help your X5 35i breathe freely mile after mile.
