Pipercross Performance Panel Air Filter for BMW 3 Series E46 Compact 320td (08/2001-07/2004) - Washable Reusable High-Flow OEM Replacement

Give your E46 Compact 2.0 diesel the airflow it deserves with a British‑made cleanable foam panel element from Pipercross. This drop‑in intake filter is designed to sit in the standard airbox on the BMW 320td Compact built between 08/2001 and 07/2004, replacing the throwaway paper element with a long‑life, high flow solution that improves response while maintaining excellent engine protection.

Why this upgrade works

• Direct drop‑in for the factory airbox on BMW 3 Series E46 Compact 320td models built 08/2001 to 07/2004
• Flow increase of up to 30 percent compared with a paper element for freer breathing and sharper pedal feel
• Flow‑bench tested to support gains in torque, drivability and potential fuel efficiency
• Three‑stage reticulated foam captures debris effectively without choking intake flow
• Extended service life vs cotton and paper elements - ideal for long‑term ownership
• Clean, dry, refit - no awkward grooves to trap dirt
• Lifetime warranty for road use
• Hand built in Northamptonshire, UK

What you will notice

Expect crisper throttle response, smoother pull through the rev range and a more consistent feel between services. We run these filters on our own cars and our customers regularly report a clear improvement in everyday drivability with the convenience of a washable, reusable panel element.

How the foam media helps your engine

Pipercross uses a layered polyurethane foam structure. The outer cell size stops larger particles, the middle layer does the heavy lifting on dust, and the inner fine layer protects the intake from the smallest contaminants. This staged approach keeps airflow high for longer while safeguarding the engine in varied UK conditions.

Easy fit - no tuning required

Swap out the old element, seat the new panel in the standard airbox and refit the cover. No ECU calibration or additional parts required. When it needs maintenance, simply clean and reuse rather than buying another disposable filter.
