Pipercross Foam Panel Element Upgrade for BMW E46 318d and 320d 136 bhp

Give your BMW E46 diesel a breath of fresh air. This Pipercross performance foam panel element is a simple drop-in upgrade for the factory air box on 318d and 320d 136 brake horsepower models built from September 2001 to September 2005. It delivers freer breathing, crisp throttle response and long-lasting protection without the need to modify your intake system.

Why enthusiasts choose this Pipercross upgrade

• Direct drop-in fit for the original air box housing. No cutting or drilling required.
• Increased intake flow compared with disposable paper media for sharper response and stronger mid-range pull.
• Flow-bench proven design that supports power and efficiency on daily drives and fast road use.
• Triple layer polyurethane foam holds more dirt than paper or cotton so performance stays consistent for longer.
• Cleanable and reusable for a lower lifetime cost than throwaway filters.
• Crafted in the UK by Pipercross and backed by a lifetime road-use warranty.

Foam technology that keeps breathing when others clog

The multi-layer foam matrix captures particles progressively through coarse, medium and fine stages. This deep filtration traps debris throughout the foam rather than just on the surface, helping your E46 diesel maintain stable airflow and dependable engine protection in real UK conditions. No fragile wire mesh, no V-shaped grooves to pack with dirt, just consistent, reliable breathing.

What you will notice

• Improved throttle response and smoother acceleration.
• Refined intake note under load without unwanted drone.
• Reduced waste thanks to a serviceable element you can clean and refit.
