K&N Replacement air filter compatible with BMW 3-Series E90 325i/330i 2005- (excl. USA) (E-2022), Heather Red

Fitted to my E81 130i this morning; decided to go with K&N over an OEM filter for a changeThey're un-oiled which is great; less risk of damage to the MAF

Highly recommend for anyone that does not want to pay £15-20 for paper filter replacement every year. If you plan to keep your car for more than 5 yrs this already pays for it self.Increases air flow and directly fits in the air box. No modification required. When washing filter remember to re-oil your k&n filter or the mesh wont filter fine particles.

Does add a little BHP to my BMW. Good quality air filter

Installed on my bmw e92 325i, not much noise difference however feels a lot more responsive on the accelerator. Doesn’t come with a sticker which is annoying. But other than that worth the buy, much more cheaper then purchasing from euro car parts or GSF

BMW feels a bit more faster, revving is faster and more free flowing. Accelerating in low rpm felt slow before and now with filter, it actually almost boosts rpm level higher in less time. Not even too loud flow sound from filter. Good product for mid power NA engine.

Awesome filter, another top qua;ity product from K&N. SIMPLY THE BEST! Gave the wonderful E92 325i better low rev power, a 0.2 lt average consumption decrease and better performance throughout the rev range. If you push it you even get a subtle roar to assure you enough air is being taken in to give you the extra power.Extremely satisfied.

This filter is not oil soaked so it was safe to install in my bmw 330i E90 m sport.No real power increases though, but didn't expect that.Easy to fit, 10 minute job.

Just what I was expecting, great product, makes induction noise slightly more aggressive. However, no K&N sticker. I don't even know if I would have put it on, but it would have been a nice addition to my sticker pile. Come on, it feels like they cheaped out here...
