Product Description

The K&N 33-2255 is a washable, reusable drop-in replacement air filter covering two distinct but related BMW platforms: the E38 7 Series 750i/750iL (1994-2001) with the M73/M73N 5.4L V12, and the entire first-generation E53 X5 lineup (2000-2006) across all engine variants from the M54 I6 3.0i through the N62 V8 4.8is. All models share compatible airbox architecture, making this a single direct-fit upgrade across both platforms. The filter seats directly into the factory airbox without modification and is fully compatible with OEM MAF sensors.

Only needing cleaning every 75,000 miles, the K&N 33-2255 is a long-term performance upgrade for owners of BMW's V12 E38 flagship and the full E53 X5 range. Whether fitted to a 750iL V12 or an X5 4.8is, this filter delivers improved airflow and throttle response without voiding the factory warranty.
