i have a couple of options buying a intercooler and want to know if there is a certain size diameter piping i should get? I want to make sure it will bolt up correctly. By the way, i have a 2001 1.8T quattro and am putting a K04-015 on. The intercooler piping size should be the best fit for the K04.Maybe someone is actually still up at 4:30 in the morning. The pic below is what im thinkin of geting, maybe bigger intercooler.

 

that intercooler is plenty big for a k04

 

what do you think i should get for pipe size tho? I dont know what would properly fit..... and whats best for A4s with a K04

 

i did 2.5 but 2.25 would be just fine
