Overview

The GetaDomTune Cylinder 4 Chamber Cooling System is a DOHC EJ Cylinder 4 Combustion Chamber Cooling kit designed to increase coolant flow in the LH head. This enhances reliability by reducing detonation-causing hot spots and improving overall cooling system performance. The kit utilizes high-grade silicone hose, custom-machined and anodized 6061 fittings, and aluminum alloy T-fittings.
Show original supplier description
The GetaDomTune Cylinder 4 Chamber Cooling System is an industry-first, patent-pending kit designed to enhance the reliability of Subaru EJ engines. It specifically targets the DOHC EJ Cylinder 4 Combustion Chamber by increasing coolant flow within the LH head. This targeted flow aims to reduce detonation-causing hot spots, lower Exhaust Gas Temperature (EGT) delta, and generally improve cooling system performance. The fittings are custom-machined and anodized from 6061 aluminum, paired with an Aluminum Alloy 5/8 T-fitting and 316SS or 304SS embossed worm clamps for secure connections. Installation includes instructions and galley plug/water pump components. This cooling system is compatible with a range of Subaru models, including the 2002-2014 WRX, 2004-2021 STI, 2004-2008 Forester XT, and 2005-2009 Legacy GT. Proper installation may require additional items such as Permatex sealant and specific tools like a deep 1-inch socket or a 3/8 crows foot, and potentially a long extension for the plug fitting. Some users have also noted the importance of having fresh coolant and acknowledged that a tune might be beneficial after installation, though this is not explicitly stated as a requirement by the manufacturer.
