Sorry if this has been asked before but I couldn't find anything. Just wondering if anyone has had experience with the K & N Air Charger. I have the opportunity to buy one at a really good price. I currently have the OEM stage 1 backing plate and mod but I was wondering if I would also need to get it re-tuned as it just has the standard Stage 1 flash.

Thanks in advance on any comments.
