BMW 535d E60 E61 (2004-2010) Pipercross high-flow panel air filter

A direct-fit, washable Pipercross panel filter for the E60 and E61 535d diesel - no trimming, no mods, no drama. Designed specifically for the M57D30 engine’s airflow demands.

• Triple-layer foam filtration - tougher on dust, kinder on your turbo than paper or cotton gauze
• Up to 30% more airflow vs stock: sharper throttle response, especially mid-range
• Clean with soap and water; no V-grooves to trap grime or degrade flow over time
• Made in Northamptonshire - consistent UK build quality, no import wait
• Lifetime warranty for road use, including fast-road and track-day duty

Not a stage 2 mod, but a sensible fast-road upgrade that works whether your 535d is stock or running mild tuning.
