Description
The Mishimoto MMOC-GTO-04 is a 25-row front-sump oil cooler kit engineered specifically for LS1/LS2-equipped vehicles, built as a DIY platform so racers can fabricate custom brackets and mount the cooler exactly where their build demands. In testing, this bar-and-plate cooler dropped oil temperatures by a massive 65°F (36°C), making it a serious tool for turbocharged and supercharged drag applications.
This Mishimoto oil cooler kit centers on a 25-row, bar-and-plate performance core finished in anodized silver, paired with a CNC-machined LS1/LS2 oil cooler adapter that opens the door to -AN fittings for a cleaner, more serviceable oil circuit. Because the cooling effect is so aggressive, Mishimoto recommends this cooler kit strictly for race vehicles rather than daily street driving. The kit also adds 1.0 qt of extra oil capacity, giving your system more volume to manage heat under sustained high-load conditions. As a fully DIY setup, it demands custom bracket fabrication and possible line modification, putting the fitment and final placement in the builder’s hands.
Vehicle Applications
This Mishimoto oil cooler kit is designed for LS1/LS2-powered, front-sump vehicles, and is confirmed for the 2004–2006 Pontiac GTO Base. Its engine-code-driven design (LS-1 and LS-2) means the fitment centers on these front-sump LS applications rather than a specific chassis, so builders should plan for custom bracket work to integrate the cooler into their GTO’s engine bay.
