Works as advertised.
My Ford 351 Windsor would run really high oil temps (280 deg). I installed this thermostat along with a Mishimoto oil cooler and now it hits 180 deg and stays put. All fittings are AN10 which can be somewhat pricey for the fittings and hose, but it made installation easy as pie. I used a Canton Racing Remote Oil Filter and run the oil to the filter, then into the thermostat and back to the remote adapter. Works like a champ.

Looks good, good packaging ...
Can only rate the unboxing. Not on the car yet... it looks well made... it's going to bridge my 19row coolers in series... cant wait:)

Solid, simple, robust, does its job very well
Worked great. Fixed my problem of Trans not getting up to temp. Going to wait til next summer to see if I need to drop to 165 thermostat. Mounting bracket made it very easy to find mounting location. And still slim enough for me as it's mounted on frame behind intake pipe.
