Free flowing sports filter for BMW 4 Series 435i 2013 to 2016

Give your 435i the breathing it deserves with a K&N cotton gauze intake filter element that fits straight into the original airbox. This cleanable, lifetime panel insert helps the turbocharged six breathe more easily for crisper throttle response, smoother acceleration and a subtly richer induction note, while still protecting your engine on UK roads.

Why choose this K&N sports filter for your 435i

The multi layer oiled cotton design reduces restriction compared with a standard paper element, helping the engine breathe more efficiently. Drivers typically notice sharper pedal response and stronger mid range pull, all while maintaining superior filtration. It is a quick DIY swap in the driveway with basic tools and the OE airbox.
