GetaDomTune Cylinder 4 Chamber Cooling Mod V6 2002-2014 WRX / 2004-2021 STI / 2005-2009 Legacy GT / 2004-2013 Forester XT
The GetaDomTune Cylinder 4 Chamber Cooling Mod was designed to 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. This helps reduce knock and detonation in cylinder #4, which is known to cause the dreaded EJ ringland failure. Keep your EJ happy by installing this kit.
