Pipercross Performance Panel Air Filter for BMW X3 F25 30d 35d (N57) 2011-2017 – High Flow Washable Drop-In Upgrade, Reusable Foam Intake/Induction Filter for Diesel xDrive 3.0D, Fits OEM Airbox

High‑flow intake upgrade for BMW X3 F25 30d and 35d from 05/2011

Unlock sharper throttle response, stronger mid‑range pull and a smoother, freer‑revving drive with this premium performance air filter element. Designed as a simple drop‑in to the factory airbox on the BMW X3 F25 diesel 30d and 35d models from 05/2011 onward, it replaces the restrictive paper insert with a multi‑layer foam construction that breathes better, filters finer and lasts far longer.

Hand made in Britain at Pipercross’s Northamptonshire facility and backed by a lifetime warranty for road use, this washable and reusable filter is a proven upgrade for everyday driving and tuned cars alike. Bench testing has shown improvements in efficiency, power and torque, with reduced intake restriction that helps the turbo spool faster and the engine breathe more easily.

Why choose this performance filter

• Direct replacement for the original air filter insert. No cutting, no modifications, fits the standard airbox.
• High airflow foam matrix provides a significant increase in breathing capacity versus paper elements.
