Unlock stronger breathing and crisp response with this UK-built, reusable performance intake element designed to fit straight into the factory airbox on your BMW 430d or 435d coupé. No modifications required, just a simple swap that delivers proven airflow gains and long-term value.

Why choose this performance intake element

• Direct replacement for the standard filter in the original airbox
• Up to 30 percent more flow compared to a paper element
• Bench tested for improvements in fuel economy, power and torque
• Triple-stage reticulated foam captures debris progressively for outstanding engine protection
• Holds more dust than cotton or paper, so it maintains performance for longer before cleaning
• Cleans easily and resists the clogging you get with traditional V-groove style frames
• Lifetime warranty for road use for unbeatable long-term value

Engineered to keep performance consistent

This advanced multi-layer foam construction uses a coarse outer layer to catch larger particles, a medium middle layer for the bulk of contaminants, and a fine inner layer to trap the remainder. The result is exceptional filtration and a stable flow rate, helping your turbocharged diesel breathe freely over a longer service interval than cotton gauze or paper alternatives.

British made quality

Hand built in Northamptonshire, this reusable intake filter is manufactured in the UK to exacting standards. Consistent materials, careful assembly and rigorous quality control give you reliable performance and peace of mind.
