i recently just purchased an arc intercooler offline used and it was only the intercooler unit. apparently there is a compression tube that usually comes with the kit and i didnt get it with it. does anyone know if you can use a greddy compression tube in place of the arc one?

 

o yea its for a s4 fc and the car is an s4 tII

 

Don't see why not, just have to get the right size coupler adapters.
