FAQ
Will the Mishimoto oil cooler overcool my FK8 in winter?
It is designed not to. Mishimoto built it as a thermostatic kit specifically to eliminate the risk of overcooling.
Do I keep the stock oil cooler?
Yes. The kit works alongside the factory liquid-to-liquid oil cooler.
Do I need to add more oil?
Yes, a little. The cooler and lines add about 0.65 qt of capacity, so top up to the correct level after install.
How long does shipping take?
Delivery times vary by part because many items ship directly from the manufacturer or distributor. Message us before ordering and we'll confirm current lead time.
Can I return it?
Yes. Returns are accepted within 30 days of delivery. The customer pays return shipping, and a restocking fee of up to 20% may apply.
