K&N Air Filter
 

Has anyone put a K&N air filter in their JCW? I'm thinking of putting one in my 2011 JCW. I usually put them in all my cars, but I wanted to check here first to see if anyone had any feedback on them in the JCW.

Yes, not problems on the JCW.

You can also look at similar products like aFe Power oil and oil free air filters.

itg air filters also.

Had a K&N oiled panel filter on my 08 MCS, zero problems.

No problem here with them or with BMC oiled filters(factory on my JCW sound kit, just make sure you oil them correctly and not over oil them. https://www.ecstuning.com/b-k-and-n-parts/v-mini/ Get the cleaning kit linked and wash them ever so often. Now the K&N motor oil filters you cannot reuse ;) For those, you can use K&P filters.https://www.ecstuning.com/b-k-and-p-...-parts/v-mini/

I have the K&N air filter in my R59 JCW and it works fine.

Yup, I've got a K&N on my 2013 R56 JCW. No problems at all.
