Pipercross Performance Air Filter for BMW 535i, 640i, 740i & X3/X4 35i (N55) - PP1984

The Pipercross PP1984 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?

Pipercross has been at the forefront of British performance filtration for over 40 years, supplying motorsport teams and road-car enthusiasts worldwide. Every Pipercross panel filter is hand-built in Britain using a multi-layer foam media that captures harmful particles while flowing significantly more air than a restrictive paper element. Unlike a disposable paper filter, a Pipercross filter is washable and reusable for the life of your vehicle — saving you money and reducing waste.

• 30–40% more airflow than the standard factory paper filter
• Washable and reusable — no need to keep buying replacement elements
• Proven foam filtration that protects your engine while improving throttle response
• Proudly made in Britain to motorsport-grade manufacturing standards
• Limited lifetime warranty for complete peace of mind
