Anyone know what size couplers to use to connect PFS intercooler? Also any suggestions on where to get them. Thanks.

 

Standard 2.75" ID, 3-inch long couplers will work just fine. You might want a slightly longer coupler for the IC duct to intake box junction (if you are using the PFS intake).

I'm happy with the couplers I got from HTS, but they can be out of stock in the more popular sizes/colors.

 

You can also order these couplers from Samco if you would like a crazy color, such as purple, yellow, orange or green. I ordered a few reducers and couplers in yellow, the only down side is it takes about 5-6 weeks because they are made overseas.

I'm going with a yellow theme in the engine bay, so the standard colors just wouldn't cut it.

Couplers were about $9.00
Reducers were $20ish
Radiator Hoses were around $125



(Also, the Samco website states that you need a minimum order of 25 couplers, but you can find distributors that can make smaller orders, PM me if you need to find one)
