Quite the opposite. So I took it out and put the stock one back in.

Anyone heard about that ? It kind of makes sense. The K and N is kind of oily when I removed it from its box.
Take what you hear from an SA with again of salt. If you want accurate information speak to the guys who actually work on the cars not the middleman between the tech and the owner.
