I'm in the process of changing my stock air filter but I've yet to decide whether I'll go for a K&N or a Green one.

I'm not that much interested in power increase but more for the improved engine noise and ease of care. Car is a Mini Cooper 1.6L manual gear box and JCW Sound Kit.

What would be your pros and cons for both of air filters? I'll probably buy them online on http://www.autoanything.com but other options are welcomed.

Thanks

 

I have a K&N. I like it. The sound improvement was not anything crazy, but definitely noticible to me.

 

Never had "green filter" so I don't know anything about it. Based on experience, I would go with K/N - it never game me problems.
