Triple-layer foam technology

Pipercross uses a three-stage foam media to capture debris without choking the intake:

• Outer layer - coarse foam to catch larger particles
• Middle layer - medium-density foam to trap the bulk of contaminants
• Inner layer - fine foam to filter the smallest dust for confident engine protection

This layered approach minimises pressure drop and keeps airflow stable, supporting a crisper pedal feel and a more engaging induction note while safeguarding your engine on UK roads all year round.
