anyhew, how in the world did you people use 3 inch couplers? i used a 3.5 to 3 reducer and BARELY got it to fit on! it took me and theJMFC about 15 minutes of pushing and pulling as hard as we could to get the dumb thing on the throttle body!
anyway, I'm really happy with mine. I didn't use an aluminum pipe (bought a u-bend on ebay, thought it was going to be aluminum, forgot to specify at the end of the auction, and got aluminized steel), but it worked out great! I got to pick my own custom angle, to put the filter right where I wanted it. I'll have to take some pics for you guys... it'* not done, mind you (need to make a box), but I took the insulation that was around the PCM and cut it up so it would form a psuedo box... and it seems to work okay. After heating the car up, there'* a noticable temperature difference between the 'hot' and 'cold' side of the insulation. once the weather is warmer, theJMFC and myself will be working on the polycarbonate box.
but I like it a lot
