Pipercross Sport Foam Intake Element for BMW 6 Series E63 E64 635d 09/2007 to 09/2011

Unlock smoother breathing for your diesel 6 Series with this UK-made Pipercross sport foam panel element. Designed as a direct drop-in to the factory filter housing on the BMW E63 and E64 635d, it replaces the stock paper insert with a high-flow, cleanable and reusable alternative that reduces restriction and supports stronger performance over a long service life.

• Direct-fit, drop-in replacement for the standard paper element in the factory housing
• Up to 30 percent more airflow compared with a typical paper insert
• Multi-layer performance foam offers excellent dust holding capacity and robust engine protection
• Serviceable and reusable for years of use, helping reduce running costs
• Helps improve throttle response and mid-range pull on road-driven diesel applications
• Lifetime warranty for road use
• UK-made at Pipercross in Northamptonshire

Why this upgrade works

Pipercross uses a progressive triple-layer foam matrix that flows strongly even as it loads with particulates, so the intake tract remains less restricted for longer. The result is a high-flow, long-interval, serviceable element that keeps filtration efficiency high while allowing the turbo diesel to draw air more freely. Expect a subtle lift in responsiveness and a durable solution that outlasts one-use paper inserts.
