Any use to change these, or stock is good enough. My 997T has 600HP at crank.
What is the best silicone hoses for 997T?

 

I hear that one of the first issues people have with added HP is the stock hoses getting lose or popping out. I got me a set of Agency Power Silicone hoses, great stuff. I am pushing about 650-700 at the crank... no issues so far.

 

If you don't change aftermarket intercoolers,stock one is ok.As long as you always check the joint clips make sure they tighted up well.Most aftermarket intercoolers EG. evoms,awe etc come with the hoses.Or the agency power hoses from vivid are great as well.I just fitted another agency power 996tt intercooler + pipes to my mate's 997tt with 600hp and they flows great.
