And don't put the oem radiator in (it sucks). A mishimoto is 2/3 the price, will last longer (it's not made of plastic at the top -- that's why the oem ones fail) and it will actually keep your engine a little cooler.

Pros: lasts longer, keeps cooler

Cons: oem ones fail

Vehicle: Subaru Impreza

I like my Mishimoto one. But I have an Auto, and the only one they had for the Baja didn't have the cooler built in, so I had to run an external trans cooler. But it all went easy, even with that. Electric fans and catch tank bolted right up no problem

Pros: easy installation

Cons: external trans cooler needed

Vehicle: Subaru

Overheating:

I spent a good chunk of change on the Mishimoto thermostat and it got stuck closed within a couple months. Needed the car back right away and all I could get was a dirt cheap MotorRad one. Darn thing has been it in now without issue for a good long while now.

Pros: working without issue

Cons: stuck closed quickly

Overheating:

I wanted to upgrade from plastic and got an aluminum Mishimoto thermostat, but i didn’t notice that it opens at 180°. Can i get away with the 180° thermostat, or should i ship it back and re-order a different, higher rated thermostat?

Pros: aluminum, upgrade from plastic

Cons: wrong opening temperature

I recommend replacing the mishimoto fans. Flow less than stock.

Cons: flow less than stock
