Why choose Pipercross foam

Pipercross uses a multi‑layer, open‑cell foam construction that flows strongly while protecting the engine from fine dust. The stacked foam layers capture debris progressively, so the filter keeps performing even as mileage builds.

• Stage 1 layer catches the larger particles
• Stage 2 layer handles the bulk of airborne contaminants
• Stage 3 layer targets the finest particulates for excellent engine protection

Compatibility
