Pipercross Plus High-Flow Performance Panel Air Filter for BMW M135i - Washable, Reusable Drop-In OEM Airbox Upgrade

Pipercross Plus panel element for BMW M135i

Give your M135i the airflow it deserves with the Pipercross Plus direct-fit panel element. Designed to drop straight into the factory airbox, this serviceable foam intake filter focuses on flow, strength and long-term durability, making it the ideal upgrade for drivers who want dependable performance from a simple, factory-style replacement.

Engineered to move more air with rock-solid support

Instead of the usual mesh surround, Pipercross Plus uses a robust 1 mm steel perimeter frame that resists flex at high volume. This reinforced design opens up the effective flow area by 22.1 percent compared to the regular mesh frame, helping your engine breathe freely through the multi-layer performance foam while maintaining excellent filtration.

Why enthusiasts choose this upgrade

• Direct-fit replacement for the factory panel element, no cutting or modifications
• High-strength steel frame for rigidity under high CFM demand
• Multi-layer foam media balances flow and filtration inside the OE airbox
• Washable and reusable for long service life and reduced waste
• Built to handle spirited road use with consistent, repeatable performance
