I have had Weapon R on my cougar for about 6 months now and it has been a pretty good intake. It makes all the right noises and looks pretty nice in the engine bay (I have an aluminum intke with red trim and dragon filter). If you are intalling an intake expection a big increase in horsepower, you will be disappointed. 5 hp is really nothing. you can't feel it. I personally like the way Weapon R looks over KKM but they are essentially the same.
