Pipercross Washable Foam Panel Air Filter for BMW X5 F15/F85 (incl M50d) 2011-on – High-Flow Drop-In Performance Engine/Intake Filter, Reusable OEM Airbox Replacement Diesel Upgrade, UK Made

High-flow drop-in intake filter for BMW X5 F15 and F85 M50d, 08/11 on

Unlock sharper response and stronger breathing from your BMW diesel with this British-made Pipercross performance filter. It slips straight into the factory airbox, replacing the stock paper element with a reusable, washable foam insert designed for serious airflow and robust engine protection.

• Up to 30 percent more air compared with a standard paper element, helping the engine breathe freely for improved drivability
• Tri-layer reticulated foam matrix captures debris across coarse, medium and fine stages, delivering excellent filtration and low restriction
• Longer service intervals than cotton gauze designs and simple cleaning to keep performance consistent
• Flow-bench tested to support gains in torque, power and potential fuel economy
• Lifetime road-use warranty for long-term value
• Handmade in Northamptonshire, UK, with rigorous quality control

Why choose this upgrade for your BMW X5 diesel

This performance intake insert keeps airflow strong for longer, resisting the clogging that hampers thin paper filters. The uniform foam structure loads evenly, avoids the dirt traps of V-wire frames and maintains consistent flow, so your X5 responds crisply mile after mile. It is a cost-effective alternative to a full induction kit while retaining the original airbox for OEM fit and finish.
