Pipercross Performance Panel Air Filter for BMW X1 E84 Diesel 16d 18d 20d 23d 25d (12/09+), Washable Reusable High-Flow OEM Airbox Replacement

High-Flow Drop-In Foam Filter Upgrade for BMW X1 E84 Diesel (2009 onwards)

Unlock smoother breathing and a crisper drive with a reusable Pipercross panel element for your BMW X1 E84 diesel. This serviceable induction filter replaces the factory paper insert inside the standard airbox, delivering increased intake flow, superb dust capture and a long-term performance upgrade for everyday road use. Ideal for X1 16d, 18d, 20d, 23d and 25d models from late 2009 onwards.

Why this performance panel element is a smart upgrade

• Simple drop-in fit for the stock airbox. No cutting, drilling or modifications required.
• Flow bench tested with up to 30 percent higher airflow versus a paper element for improved breathing potential.
• Triple-layer foam matrix offers outstanding dust capacity and consistent filtration.
• Longer service intervals than many cotton gauze filters. Designed to keep flowing as it loads.
• Washable and reusable to reduce waste and ongoing costs.
• Road-use lifetime warranty for replacement filters.
• Crafted in Northamptonshire, England by Pipercross.

Three-layer foam technology that keeps performing

The multi-density foam construction maintains strong airflow even as contamination builds, helping your diesel X1 breathe freely for longer. Each layer plays a role in staged filtration for reliable engine protection:

• Outer layer: coarse foam arrests larger particles and grit.
• Middle layer: medium-density foam captures the bulk of airborne debris.
• Inner layer: fine foam targets the smallest particles before the intake.

Where thin paper media can become restrictive, this foam matrix resists clogging and supports steady torque and response over extended mileage.

Real-world feedback

We run these Pipercross panel filters on our own cars and customers consistently report sharper throttle response, a cleaner induction note and low-maintenance ownership. It is a fit-and-forget upgrade that pays for itself over time.
