How the multi-layer foam works

Pipercross uses a three-stage foam structure to capture debris without choking intake flow. A coarse outer layer arrests larger particles, a medium core traps the bulk of contaminants and a fine inner layer protects the engine from the remaining dust. Unlike thin paper pleats or cotton gauze that can clog quickly, the depth-loading foam keeps CFM high for longer service intervals and consistent performance.
