BMW Z4 E89 35i sDrive 2009 to 2017 performance panel element by K&N, a direct-fit upgrade for the factory intake that improves engine breathing, throttle response and sound

Give your roadster the crisp response it deserves with this genuine K&N panel element tailored for the BMW Z4 E89 35i and sDrive35i. This serviceable, cleanable cotton gauze insert slides straight into the original airbox, keeping OEM fit and finish while allowing the engine to inhale more freely. Expect a sharper pedal feel, a subtle induction growl and long-term savings compared with throwaway paper filters. No remap needed, no extra parts required, just a simple swap that works seamlessly with the standard ECU.

We run these filters on our own cars and have installed them for many MJ Modifications customers across the UK.
