Torque Solution Cylinder 4 Coolant Mod for EJ WRX/STi (TS-SU-585)

The Torque Solution cylinder 4 coolant mod for 02-14 WRX and 2004-2021 STi was designed to increase coolant flow to the cylinder #4 head area. This additional coolant flow helps reduce cylinder #4 coolant temps and keeps the temps more uniform compared to the rest of the cylinders.

This will help 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! Includes CNC machined billet aluminum head and T fittings along with a multi-layer silicone hose and stainless steel clamps.
