GNP's Cylinder 4 Coolant Mod was designed for Subaru EJ Engines to help increase coolant flow to cylinder 4 head area. The additional coolant flow helps reduce cylinder #4 coolant temps and keeps the temps more uniform with the rest of the cylinders.

Doing this helps reduce knock and detonation in cylinder #4.
