Description

The Blox Racing Cylinder 4 Coolant Flow Upgrade Kit is designed for Subaru EJ20 and EJ25 engines. It addresses a known cooling design oversight in the left-hand cylinder head's #4 cylinder, which tends to run hotter due to insufficient coolant flow. This kit aims to increase coolant circulation to cylinder 4 by drawing flow from the water pump, thereby minimizing the risk of overheating and detonation.
