Looking for ideal fluid temperature regulation for your next project? Mishimoto has the answer with our innovative, ingenious in-line oil thermostat. This sleek unit features a perfect blend of both form and function, and is precision-engineered to properly regulate engine oil, transmission fluid, or any other driveline fluid. The Mishimoto In-Line Oil Thermostat is CNC-machined from a single piece of billet 6061 aluminum. This component is ideal for projects where space or clearance places a constraint on using a standard oil sandwich plate. The included thermostat regulates temperatures at 185 degrees Fahrenheit, which is easily interchanged with our 160 degree and 200 degree thermostat units to accommodate to any project. This in-line thermostat includes four -10AN fittings with dowty seals for leak-free line connections. Additionally, this thermostat includes a CNC-machined heat-sink which provides an enhancement in style and helps to reduce fluid temperatures. This also includes a universal mounting bracket and the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
