Pipercross Plus Performance Air Filter for BMW M340i, M440i, M240i & Z4 M40i (B58) - PP2020PLUS

The Pipercross Plus PP2020PLUS is a high-flow panel performance air filter that drops straight into your factory airbox as a direct replacement for the original paper element. It flows significantly more air than the standard filter to improve throttle response, engine breathing and efficiency — with no airbox modification required. Like every Pipercross filter it is washable, reusable and built to last.

Why Pipercross Plus?

The Pipercross Plus range is the premium tier of the Pipercross panel filter line-up, developed for the fast-road, luxury and supercar markets including BMW M, Audi RS, Ferrari and Lamborghini. It pairs a hybrid multi-laminate foam with an industry-first, CNC laser-cut 0.9mm stainless steel backing frame.

• 22.1% more effective airflow than a standard mesh-backed panel filter
• Dual-layer foam: a 20mm layer of free-flowing 20 PPI foam captures larger particles, backed by a 5mm 60 PPI layer for fine filtration
• 0.9mm CNC laser-cut stainless steel frame for increased rigidity and durability
• Washable and reusable with a limited lifetime warranty
• Designed and made in Britain and flow-tested in-house
