The GetaDomTune (GDT) Subaru EJ Cylinder 4 Combustion Chamber Cooling Kit (otherwise known as the Cylinder 4 Cooling Mod) increases coolant flow in the left-hand cylinder head. The manufacturer claims that improving the coolant's flow improves reliability by reducing detonation causing hot spots. It might even be true!

- 2002-2014 Subaru WRX
