Garrett intercooler

[Kieron]

I bought a new garrett core intercooler from a shop who had built it and a motor for a Civic owner who reneged on him. It's a garrett core #703518-6015 and it has 2.5" inlet and outlet.

I'm using an apikol smic at the moment on motoza 1+.

Is there anything to be concerned about regards those inlet/outlet sizes if it was to be fitted to my 2003 A4 1.8 quattro auto?
Also, I can see lots of options for universal ic piping but is there a reliable set that anyone would particularly recommend?

thanks

Use transition couplers. But my advice is just stick with the Apikol SMIC. And if you move up in turbo size, then consider using it. Meanwhile it can sit around as extra cash for those rainy days (CL is quick sale, depending).
