High-Flow Foam Panel Filter Upgrade for BMW 3 Series F30/F31 316i 318i (2012 on)

Let your 3 Series breathe properly with this hand-built British foam panel insert from Pipercross. It swaps straight into the standard air box to unlock faster throttle response, smoother acceleration and stronger mid‑range pull while safeguarding your engine with outstanding filtration. Washable and reusable, it is a smart long-term upgrade that saves money versus disposable paper elements and reduces waste.

• Direct-fit replacement for the factory panel element in the OEM air box
• Flow increase of up to 30 percent compared with a standard paper filter
• Triple-layer performance foam for high airflow and superb dust capture
• Serviceable and washable for repeated use and low running costs
• Consistent performance for everyday driving and fast-road use
• Easy to clean with no wire grooves that trap dirt
• Hand built in Britain, backed by a lifetime warranty for road use

Why choose performance foam over paper or cotton

The multi-layer foam media offers exceptional dirt-holding capacity, meaning it keeps flowing freely for longer. A coarse outer layer stops larger particles, a denser middle layer handles the bulk of contaminants, and a fine inner layer protects the engine from the smallest debris. The result is high airflow, excellent protection and longer intervals between cleans compared with typical cotton gauze and paper elements.
