It slides straight into the standard air box with zero cutting or drilling, delivering a noticeable flow increase and long-lasting engine protection.

Why this free-flowing foam filter is a smarter choice

• Direct fit in the factory air box - simple swap for the paper element
• Significant airflow gains versus paper media for sharper response and smooth acceleration
• Serviceable, cleanable and reusable - cut recurring filter costs
• Triple-layer foam offers high dust holding capacity for consistent performance between services
• No fiddly grooves to trap debris - easy to maintain at home
• Tested for improvements in power delivery, torque and potential fuel economy
• Lifetime warranty for road use
• Hand built in the UK with quality materials and precise fitment

Triple-layer foam that keeps flowing

Pipercross uses a multi-density polyurethane foam construction that captures contaminants across three stages while keeping intake restriction low. The outer layer arrests larger particles, the mid layer handles the bulk of incoming dust, and the inner layer screens the finest matter. This architecture maintains stable airflow for longer than paper or thin cotton media, helping your 335i breathe freely between service intervals.

Trusted by us and our customers

We run Pipercross on our own cars and customer feedback has been consistently positive. Expect a responsive feel, dependable filtration and straightforward cleaning. It is a proven, cost-effective alternative to one-use paper filters and a neat solution if you want an intake upgrade without fitting a full induction kit.
