Improved Racing Product Reviews
Works as advertised and I'm no longer concerned about it taking forever for oil temp to come up on street. I have the 45degree fittings to allow for my 4" grill mounted brake ducts. Kit was a straightforward installation with great instructions and very well made with high quality components. Only small hassle getting the bolts holding the t-stat started. Very satisfied.
Perfect for my application
Worked perfectly for a replacement sensor, as I installed a oil cooler block that only had 1/8npt taps. Super fast shipment. Thanks guys!

Superb quality stuff. Installed this in my E36. Oil stays at desired temperature, just as Michael said it would. I'm really glad I did add this to my oil cooler system. After warming up temperature stays above 101 degree Cel, even while driving at night and/or heavy rain. Oil is kept at stable temperature and thus at nice pressure. THANKS.
Works exactly as claimed
The FSM thermostat replaced a MoCal thermostat in my 3.6 air cooled kit car, which has a huge oil cooler (7" x 22" x 4" thick) that has almost no pressure drop across it. The MoCal was very similar to having no thermostat at all - the oil never got warm except during track usage. The FSM actually lets the engine oil get up to temperature on most days. Seems very well made. Highly recommended.
