any one fitted one ? can only find k&n listed for my car (2.5 n52) but the oil on these can mess up the maf sensor , i prefere the green cotton ones but not sure if it fits my car

Not disimilar here - I have the K&N on and it's not a jot different to the OEM in performance
Long threads and good research on here in the past that shows the OEM BMW is better than aftermarket form a filtration and air flow perspective.
You wouldn't say that if you'd seen the amount of crap burnt on to the MAF wires of e34 M5s (they go through a regular hot wire cycle to try to burn off contaminants).lacroupade said:urban myth :wink:



i ve seen this problem on vag 2.0 tfsi engines too, can use oiled filters but need to wipe xs oil off firstmmm-five said:You wouldn't say that if you'd seen the amount of crap burnt on to the MAF wires of e34 M5s (they go through a regular hot wire cycle to try to burn off contaminants).lacroupade said:urban myth :wink:
I don't really have any problem with non-oiled performance filters, just think they're overpriced for something that arguably does a worse job (i.e. filtering).
Even some of the M5 tuners recommend non-oiled versions for the M5 for just this issue - although they word it as "dry filter - so will not foul the expensive M5 MAF sensor".

Just a 15 minute mod to do this and fairly inexpensive based on other member's feedback and a huge bimmerforums thread about this one, so I just had to try it![]()
