Improved Racing's Flow Series Motorsport (FSM) oil thermostat is a universal solution that can be used with any fluid cooler on any vehicle, industrial or lab application. The device's unique patent-pending internal design ensures a low pressure drop by placing the bypass valve mechanism completely out of the primary oil flow. This arrangement also allows for a compact design. This thermostat is designed for use in low-temperature applications such as transmission and differential coolers and maintains a minimum temperature of 145°F (63°C) +/- 2°F exiting the transmission or differential in most conditions. It features female -10AN O-ring boss threads and comes with -12AN fittings. The included brackets allow for multiple mounting options.

• Reduces excessive engine wear and horsepower losses while improving gas mileage by preventing oil temperatures from dropping below optimal levels. Maintains a minimum fluid temperature of 147F (63.8C) +/- 2F in most conditions
• Proprietary high flow, low pressure drop design locates the valve assembly completely out of the primary fluid flow
• Allows a small percentage (less than 10%) of fluid to continually circulate to eliminate air pockets and prevent cold fluid trapped in the cooler from shocking the system
• Lightweight (12.7 ounces, or 360g, without brackets or fittings), rebuildable, and constructed from 6061-T6 billet aluminum with a black anodized finish. Female -10AN O-ring boss threads. Includes four black anodized aluminum fittings with Viton O-rings for -12AN lines included
• Made in USA. Lifetime manufacturer's warranty
