K&N E-2021 Performance Panel Filter for BMW Petrol Models

Give your BMW a simple, proven breathing upgrade with the K&N E-2021 serviceable panel element. This high flow cotton media insert replaces the factory paper part inside the standard airbox, boosting intake efficiency, sharpening throttle response and delivering reliable filtration for thousands of miles. Washable and reusable, it is a smart long-term upgrade for everyday driving and spirited road use alike.

Part number: E-2021

Why it belongs in your BMW

  • High flow cotton gauze media that promotes better intake efficiency and crisp pedal response
  • Washable and reusable construction for long service life and reduced waste
  • Direct-fit drop-in element for the factory airbox with no cutting or coding
  • Durable build quality with excellent filtration for petrol engines
  • Great value compared with repeatedly buying disposable paper inserts

We use the E-2021 on our own cars at MJ Modifications and have fitted it for many happy customers. Feedback consistently highlights the quality feel, easy installation and noticeably freer breathing.
