think I messed up... intercooler help

Capone13 · 07-09-2023, 01:37 AM

Today I was on marketplace and saw an ad for an n55/n54 csf intercooler. Price was good it was barely even used so I grabbed it. Now I have come to realize the inlets to the intercooler are not the same from n55 to n54 (c clamp difference only) and he sold me an n55 only intercooler. Is there any way I can make it work since I got it for such a good price or should I just sell it and keep searching? The one with the chrome ends is the one I should be using for my n54 and the one with the arrow over it is the one I purchased.

it is the same... one just needs aftermarket intercooler piping too which comes as a separate kit with moist brands. Some come with the intercooler piping.

Agreed as above. Will just need silicone couplers and T clamps.

Used these T clamps for some of my own work, and for silicone couplers would just recco measuring what you need for each inlet / outlet diameter and grab anything with some good reviews. I used these for my outlet coupler but most high temp silicone should work fine!
