i want to perform this mod and wonder how many 4th genners have it and do you have pics, step-by-step instructons. thanks, Anton

 

i think that dave b has some pics and instructions. i just put in a 3" hose and used a fram filter. haven't installed the place racing upper piece yet but i should get it on tuesday. i don't think i made any extra HP but i didn't lose any either when i switched from the stillen intake. times at the track are the exact same as with my stillen intake but mph went up a little.
