Why choose a Pipercross foam panel filter

Pipercross uses multi-layer foam technology rather than cotton or paper. Foam offers significantly greater dust holding capacity, so your BMW 635d air filter flows stronger for longer and helps maintain peak performance over extended mileage. The triple-layer design features a coarse outer layer to catch larger particles, a medium middle layer to trap the bulk of debris and a fine inner layer to capture the remaining particulates. This progressive filtration provides exceptional engine protection in all conditions while supporting high airflow.

Proven performance and low maintenance

With up to 30% more airflow than an OEM paper element and bench-tested gains in fuel economy, power and torque, this Pipercross panel air filter is a smart, cost-effective performance upgrade for the BMW 6 Series E63 E64 635d. Cleaning is straightforward and the foam construction avoids the dirt build-up issues common with thin, V-frame paper or cotton elements. It is a fit-and-forget solution with a lifetime warranty for road use.

  • BMW 6 Series E63 E64 635d 09/2007 to 09/2011
