High-Flow Reusable Panel Filter for BMW E46 325 Models

Give your BMW 3 Series breathing room with a quality K&N high-flow cotton gauze panel element designed for the E46 325i, 325Ci, 325Xi and 325ti Compact from 2000 to 2005. This direct-fit, serviceable intake filter drops straight into the factory airbox and lets the engine inhale more efficiently while maintaining excellent filtration. It is a lifetime filter you can clean and refit, delivering crisp throttle response and a more purposeful induction note without the need for a full intake kit or any ECU changes.

Our team at MJ Modifications has installed these on many customer cars, and feedback is consistently positive. Drivers report sharper pedal response, smoother mid-range pull and the satisfaction of not having to buy disposable paper elements again. It is a simple, effective upgrade for daily driving and spirited B-road use.
