Works great for my mustang
The included clamps were tossed. I put these on my fox body coolant thing to just loop it and bypass the heater core

Works perfect
Fit like a glove on my 2002 Camaro Z28. Held up well. Would buy again.

Heater hose bypass
Easier to bypass heater hoses on ls swap

It will get you out of a jam if you blow a heater hose. Handy to have.
The fit was perfect. Needs to come with standard clamps. The factory spring clamps are hard to work with on the road.
