Pipercross Performance Panel Air Filter -

Performance Foam Panel Insert for BMW E81 E82 E87 E88 135i and 1M Coupe

Give your E8x 1 Series intake a serious upgrade with a genuine Pipercross foam panel insert. This serviceable, cleanable element drops straight into the factory airbox, boosting intake flow and response while maintaining excellent engine protection. Hand built in Britain and designed to outlast disposable paper filters, it is an ideal tuning-friendly intake refresh for road and track.

Why enthusiasts choose this filter

• Direct replacement element for the OE airbox - no cutting or drilling
• As much as 30 percent better airflow when compared with a standard paper element
• Long service intervals versus cotton gauze alternatives
• Easy to clean - no V-shaped wire grooves to clog with dirt
• Flow bench development supports improved throttle response, torque delivery and fuel efficiency
• Lifetime warranty for road use

Triple-layer foam technology

Pipercross uses a multilayer reticulated foam construction to balance maximum flow with outstanding filtration, helping your BMW deliver consistent performance in all conditions.

• Outer stage: coarse foam captures larger debris
• Middle stage: medium density layer traps the bulk of contaminants
• Inner stage: fine foam protects the engine from the smallest particles

The progressive depth loading design maintains strong, stable airflow for longer than thin paper or cotton elements.

Compatibility

Designed to fit:

• BMW 1 Series E81 E82 E87 E88 135i
• BMW 1M Coupe
• Build date 09/2007 onwards
