Real-world benefits on the 320td Compact
The Pipercross performance air filter increases intake airflow while maintaining excellent filtration, helping your diesel 320td breathe easier. Expect crisper throttle response, stronger mid-range pull and smoother drivability. We run Pipercross filters on our own cars and our customers consistently report a noticeable improvement in responsiveness with the convenience of a washable, reusable panel filter that keeps performing.
Foam technology that flows stronger for longer
Unlike paper or cotton filters stretched over wire frames, Pipercross uses a multi-layer polyurethane foam. The outer coarse layer captures larger particles, the middle layer traps the bulk of the debris and the inner fine layer catches the remainder. This triple layer design keeps airflow high and stable for longer, helping the engine maintain peak performance between services while delivering exceptional protection in all conditions.

This BMW E46 320td panel filter drops straight into the standard airbox with basic tools. It retains the factory look and induction path, with no ECU tuning required. Clean, dry, refit and drive. A smart upgrade over a disposable paper element and a cleaner long term solution than many cotton filters.
