Hi there,
Im new to this whole forum thing but anyways.... I want to install a front mount intercooler on my car which is the 225hp audi tt. However i dont know what size of intercooler to get and on top of that, I would much prefer to build it myself rather than get a kit which can cost up to $1200. Any suggestionson where to start? i was thinking an ebay intercooler and buy my piping somewhere else but i cant find a "somewhere else" that sells good 2.5" piping that is exactly what i need. I dont want extra piping and i dont want not enough. Where can i find couplers as well?

Thank you!

 

it already has twin intercoolers......
