Torque Solution Cylinder 4 Coolant Mod (Part Number: TS-SU-585) is built for Subaru EJ Engines. Torque Solution Cylinder 4 Coolant Mod for Subaru EJ Engines 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 Torque Solution's kit. Quality was Torque Solution's #1 priority which is why Torque Solution's kit includes CNC'd billet aluminum head and T fittings along with a multi-layer silicone hose and stainless steel clamps.
