what size couplings?
 

I just received Tyrus intercooler and his intercooler inlet/outlet is 2.5" And my question is that what size couplings do i use to connect the inlet/outlet to the 2.5" Mandrel chargepipes?

I went to home depot to look for some couplings. But i only found some 2" couplings but i think its a bit small. Then I bought some 3" couplings. But it was too big. What can i do?

Go to Napa auto parts, and they have some silicone hose, its some nice black rubber ----. Looks like heater hose, you will have to buy it by the foot, but get 2.5in and it works great with his IC's.

Also try boat supply/parts stores..

NAPA charge me $40 per feet for the silicon hose. Total of 3 feet and he said he can not cut it for me. So $120 for a silicon hose is expensive.

any other suggestion? How much you got yours for Jeff? What is the part number at NAPA?
