I installed a Saleen Series IV and think it is a good kit for a street machine. Yea it is not a KB but it was all I wanted to spend. Remember it is just one of many mods I plan for the car. The intake is not the best, but they have to keep Ford happy, I guess. I had to wait 2 months for the kit and it was missing some parts but they shipped them next day. The only problem I had was the installation manual, or lack of ! The manual is crap, but I worked my way through it and think my installation was better anyway. The parts list leaves a lot to be desired also. I picked the Saleen because of the Whipple SC and want something reliable to drive eveyday. Saleen has a nice intercooler, so if you go KB look at the possibility of a Saleen intercooler.
