Subaru OEM Thermostat
Subaru EJ Models (inc. 2004+ STI / 2002-2014 WRX)
Features & Product Details
If you are experiencing overheating issues and you know that your head gaskets are fine and that your other cooling components are in check, then chances are that you need a new thermostat. The intended purpose of a thermostat is to block the flow of coolant to the radiator until the engine has warmed up. If your thermostat is broken, then it could stay closed which would block the flow of coolant to the radiator.
If you need to replace the thermostat in your vehicle, sometimes going to your local auto parts store may not be the best solution as they can oftentimes provide mass produced yet inferior products.
This is an OEM Subaru component that is the same component that came in your vehicle right off the assembly line.

Works better than the one the garage put in my car a year ago
Unless you really, really, REALLY know how to build a racing engine, and how to actually ENGINEER an engine for heat tolerances, expansion properties of the various materials in use, optimal oil temperature, etc., then don't bother with an aftermarket "upgrade" for your thermostat. Subaru designed this thermostat to keep your engine at a specific operating temperature for a number of reasons, and changing that equation by more than a few degrees is likely to throw the balance of your engine, oil system, etc. off. If you need "extra" or "better" cooling capacity, go with the OEM thermostat and a performance radiator. This will allow for the thermostat to open and pass coolant through the engine as needed, while still providing for that "extra" cooling capacity you "need" (seriously, unless you've got some crazy mods in your car, the OEM cooling system is adequate).
OEM! What do u expect! Does its job well.
Perfect oem replacement thermostat. Don't need to get anything else.
Bought it when I bought my gates timing belt kit for my 05 wrx. Came as described I only use OEM parts when it comes to timing kit. It doesn't come with the gasket so either make sure you get one with the timing belt kit or you order one separately. Never a bad idea to have a spare
