  • Up to 30% more airflow compared to a standard paper filter
  • Longer service life before cleaning is required versus cotton filters

  • Lifetime warranty on all replacement and performance road-use filters
  • Manufactured in the UK for consistent quality and fitment

Engineered for airflow, filtration and durability

Pipercross uses multi-layered, triple-density foam technology instead of paper or cotton. This advanced foam construction has a larger filtration capacity, so it maintains high airflow for longer. In real-world driving, that means your BMW X4 F26 M40i continues to breathe freely while paper or cotton filters begin to restrict.

The triple-layer foam is designed to protect your engine in all conditions:

  • Outer layer: coarse foam to capture larger particles
  • Middle layer: medium foam to trap the bulk of contaminants
  • Inner layer: fine foam to catch the remaining particulates

This multi-stage design delivers excellent filtration without sacrificing flow, helping sustain power and torque while extending service intervals. All Pipercross filters are hand-made in Northamptonshire to strict standards, so you get reliable, repeatable performance from a proudly British-made product.
