Show original supplier description
The GetaDomTune Cylinder 4 Chamber Cooling System is an industry-first, patent-pending DOHC EJ component designed to improve engine reliability. This kit specifically targets cylinder 4 by increasing coolant flow in the LH head. This enhanced flow helps reduce detonation-causing hot spots, lowers Exhaust Gas Temperature (EGT) delta, and boosts overall cooling system performance. The system is constructed with quality materials, including a high-grade silicone hose, a stainless pinch clamp, and a custom-machined and anodized 6061 fitting for the coolant pipe. Additionally, three 316SS or 304SS embossed worm clamps are included for secure installation. An instruction sheet is provided to guide the user through the process. This cooling system is compatible with a range of Subaru models. It fits the WRX from 2002-2014, the STI from 2004-2021, and the Legacy GT from 2005-2009. It is important to note that this kit fits all EJ years and models *except* for the 2010 and newer Legacy GT models. The patent-pending design aims to provide peace of mind and improved thermal management for these specific EJ engines.
