High quality piece
Definitely worth the money IMHO. Activates well and is accurate. Put this on my ‘95 5.0 Mustang Cobra with an aluminum gasket with built in seals + a bead of gasket sealer for good measure when replacing water pump and thermostat housing. No drips, runs or errors!

Nice thermostat, well built
Nice! the build quality is obvious, and the flow paths look to be optimized.
