Not satisfied with the purchase. I installed these hoses on my 2004 WRX with a Mishimoto X-Line radiator and the upper hose wore out from stock fans after the first day of riding. We even cut the top tube twice because after the first cut it was clear that the tube needed more cutting. There is so little space between the radiator and the fan that the upper hose expands too much when the coolant heats up. If the hoses fit straight and didn't have to be shortened, they might hold up better. If you have a 2004 WRX with stock cooling fans, be prepared to buy Gates, OEM or whatever.
