I put a short ram intake on my '04, with k&n's in the airbox, and two conical *sp* style filters. If i want to race, or am not driving to work, i put the stock intakes on. I loose horsepower with the shorties on. The installed them just to figure if i liked them or whether i would get any gains. With my comp tech gauge, i run slower with them on. I still however use them when i drive to work because i live at 6 thousand feet and drive up to almost 10 thousand feet and have sand and gravel and a lot of "crap" in the air. So i just figure it keeps my engine from sucking in any crap into the valves. Ps and I made it myself with some parts from a local hot rod shop, doesn't look bad, minus they ordered two different colored filters (*Grumbles*) Now if somebody would buy me a second hood? I would be more than happy to cut it up and make a true ram air intake for this car. *Rubs his hands in eager awaiting with an evil grin* lol.
