How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

What if I need to return a product or it’s defective?

Most unused items can be returned within 30 days in their original packaging. Some products are covered by a manufacturer’s warranty as well. If something arrives damaged or doesn’t meet your expectations, just let us know — we’ll help you get it replaced, refunded, or repaired. (Tracking updates are also emailed automatically once your order ships.)

What's the lead time on custom or fabricated parts?

Many of our parts are built to order — especially fabricated or performance components. These can take additional time to produce before shipping. Lead times vary by manufacturer and demand, but we’ll always keep you updated along the way.

Description

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.
