I have debated this as well from what I gather I am going with Post MAF tubes w/ K&N drop ins. My take is if you aren't going with the Stillen Gen3 or AEM version 2 long tube intakes you aren't gaining much over the stock air boxes with the short ram offerings other than getting smooth tubes and different filters. So cut the difference and grab the Post MAF tubes to smooth the air flow out and add the K&N filters for better air flow through the filter. It also comes down to what you want the car to be...the best performance you can get for your money or just want to open it up a little more. That is my
