Pipercross Performance Panel Air Filter | BMW 3 Series F30/F31 330d 335d (2012+, N57 Diesel) | High-Flow Washable Reusable Foam Drop-In Replacement | OEM Airbox Intake Upgrade Saloon/Touring

High-flow foam upgrade for BMW F30 and F31 330d and 335d diesel models from 2012+

Unlock smoother induction, sharper throttle response and stronger mid-range pull with this premium drop-in intake element from Pipercross. Designed to sit in the factory airbox, it is a direct-fit performance upgrade for BMW 3-Series F30 and F31 diesel variants 330d and 335d, delivering a freer-breathing engine without extra noise or the hassle of a full cone intake.

Why choose this performance intake element

• Up to 30 percent higher flow compared with a standard paper element for reduced restriction and improved engine breathing
• Three-stage foam matrix captures particles progressively for excellent dust retention and long service life
• Washable and reusable for lower running costs and extended service intervals
• Simple maintenance and easy refit into the original airbox
• Bench and dyno proven for better efficiency, power and torque characteristics
• Lifetime guarantee for road use
• Proudly made in Britain with hand-finished quality

Foam technology that keeps flowing

Unlike thin pleated paper or cotton media that can clog quickly, Pipercross uses a multi-layer foam construction. A coarse outer layer stops larger debris, the mid layer handles the bulk of contaminants, and a fine inner layer protects the engine from the smallest particles. This progressive filtration keeps pressure drop low for longer, helping your BMW maintain peak performance between services.

Real-world results

We run this upgrade on our own vehicles and customer cars. Feedback is consistently positive, with owners noticing crisper throttle response, stronger acceleration and, in many cases, a welcome improvement in MPG during steady cruising. It is a true fit-and-forget induction enhancement that makes your diesel six feel more alive.
