Why enthusiasts choose this upgrade

• Direct fit for the factory air box - no cutting, drilling or remap required
• Up to 30 percent more flow versus a stock paper element for improved response
• Flow bench tested with proven gains in torque, power and potential MPG
• Extended service life before cleaning compared with many cotton alternatives
• Easy to wash and re-oil, with no V frame to trap dirt and reduce performance
• Made in Britain, hand finished quality and lifetime support for road use

Foam technology that keeps performing

This insert uses a multi layer reticulated foam stack engineered to trap particles progressively. A coarse outer layer intercepts larger debris, a medium middle layer handles the bulk of contaminants, and a fine inner layer protects the engine from the smallest particles. The result is high filtration capacity and low restriction over longer service intervals, helping your diesel breathe freely in real world conditions.

Vehicle compatibility

• BMW 3 Series 325d E90 saloon, E91 Touring estate, E92 coupe, E93 convertible
• Production years 09/2006 to 03/2010

Please compare your air box and year of manufacture to confirm suitability for your specific 325d before ordering.
