I have a 06 w6spd trans. It needed a skid plate when i bought it. So i fabricated one from diamond plate. I also made my shifter **** from alum. My intake scoop from a solid piece of 4"x7" alum. 1" thick which i first cut and shaped and rolled to the curve of my cars nose. Inside is stainless screen. And because of where i felt was the best location i had to cut the foam backing behind the bumper. I formed a duct of 20 g aluminum for a smoother draft and better appearance. I fabbed an alum box that has glass and foil insulation on the engine side. I have a Specter performance airfilter which is adjustable to 4". I have about 8" of .125 x 4" alum tube a rubber reducer to a 3.25 id plastic tube that ive epoxyed my maf sensor into. So its 6" that is just a little wider than stock in almost the same location. I attached the vacum line just downstream of the maf. So i avoided any reprogramming issues. I did the last 12" w 4" alum dryer duct. Been running this for over a year. I love it. But now its time to smog. With all factory hoses hooked up think it will pass smog? Oh yeah I also tested it for any air leaks
