I have the K&N short ram, I didn't dyno it thus I can't tell you how many horses we are talking about, but it does breath better especially from 3000rpm and up compare to a K&N drop-in, (Yes, I had the drop-in prior to the short ram)
For under $300 I think it's a good investment both performance and price.
Plus no cutting or whatsoever, even to wash the filter is easy cos you don't need to take off the bumper.
