i was changing my oil filter today and took out my air filter (scotty 3) and intake hose for better acess to the oil fiter. here is my question. the hose the comes off the side of turbo goes into the inter cooler to cool the air. they are hard platic and rubber hoses. there is a small section of hose that conects the two looks like so that the motor can flex without braking anyting off and my hose is peeling strings off it. why is it not a rubber boot or rubber material? looks like it should be leaking, but the truck runs good. do i need to replace it?
