It drops straight into the standard airbox, so you get an instant induction upgrade without cutting or modifying anything.

We run these filters on our own cars and our customers love the extra liveliness and value for money. If you want a simple, serviceable upgrade that performs on British roads, this is a brilliant choice.

• Direct swap for the factory airbox element. No tools beyond standard hand tools
• As much as 30 percent more air delivery compared with a paper element
• Flowbench validated for gains in drivability, torque feel and fuel efficiency
• Retains performance for longer service intervals than cotton gauze styles
• Washable and reusable foam construction for long term savings
• Triple layer reticulated foam for high flow with excellent engine protection
• Lifetime warranty for performance road use
• Crafted in Northamptonshire, England

Why a performance foam filter

Multi layer reticulated foam holds far more debris before restriction starts, so it keeps flowing even as miles rack up. The three stage matrix is engineered to catch progressively smaller particles while maintaining low restriction, helping your diesel BMW breathe freely in all UK conditions.

• Outer coarse layer captures larger dirt
• Middle layer traps the bulk of contaminants
• Inner fine layer stops the remaining fine particles

The result is a reusable induction filter that supports consistent power delivery, smooth acceleration and reliable filtration without the drawbacks of thin paper or cotton media.
