Performance Cotton Panel Filter for BMW X3 E83 3.0i 231 bhp 2003 to 08/2006

Give your straight six X3 the breathing it deserves with a genuine K&N cotton gauze panel element. This direct-fit insert drops straight into the factory airbox on the E83 3.0 litre petrol and increases airflow for sharper throttle response, stronger mid-range pull and a crisper induction note, all while maintaining outstanding engine protection. It is washable, reusable and built to last with the famous K&N Million Mile Limited Warranty.

Why choose this upgrade

Freeing up the intake side is one of the simplest ways to enhance response on the 3.0 litre petrol. The K&N panel element offers high flow with excellent dust-holding capacity for day-to-day road use in the UK. Expect a subtle but noticeable induction tone under load, improved responsiveness around town and effortless mid-range on A-road overtakes. Clean it with a K&N service kit when required and refit for years of performance.
