when are upgraded boost hoses really needed? At a certain HP level? At intercooler upgrade? and who has the best hoses out there bang for buck.. thanks

 

Is there any advantage to doing only the F hose?

 

I am running 1.1 - 1.3bar on Stock Hoses. They are apparently good to 25psi or so. I did the "F" hose but did not really need it, I would not do it again, I would leave the stock hose and change the diverters. Some here have gone with the Cheaper Silicone hoses with good results. That would be my choice. Unless you like the bling! Then go with the $250 set you can see on eBay.

I am going to remove my AP "F" Hose and put the stock one back. Then sell my AP.

 

The real issue is age and increased pressure. Some folks will drive their cars for many years at stock levels without issues. Others will have hose issues as they increase power. I upgraded mine a while ago (summer 2007) to SAMCO hoses and have been very happy with their quality, fit and performance!

There are other options as well... I've seen the agency power units and they look identical to the SAMCO hoses...
