While we talking Air - Any idea if there's any value or decent gain difference to replace a OEM filter with a K&N or any other performance filter for the stock setup?

Just dont waste your money on Tweek DCI's or any airfilter from them ... They do the job but quality is not up to scratch compared to others in the same price range.
