Mishimoto 04-06 Pontiac GTO 5.7L/6.0L Thermostatic Oil Cooler Kit - Silver

LS series engines are simple, powerful, reliable machines, but no engine can deal with high oil temperatures. To cool the GTO's massive engine, we picked our largest oil cooler for the job. The 25-row stacked-plate cooler will have no problem making sure oil is at an optimal temperature. On the other end of this GTO oil cooler kit is a specially designed oil line adapter that bolts to the oil filter housing to allow for the attachment of our --AN stainless steel lines. The tight space restrictions eliminated the possibility of using a thermostatic sandwich plate, which we use on most of our other direct-fit oil cooler kits. Instead our In-line Oil Thermostat is used to regulate oil temperatures. This meticulously designed thermostat mounts under the headlight by means of its own direct-fit bracket, and will make sure your oil stays at a happy 185 F. During the testing process of this GTO oil cooler, the in-line thermostat was not used in order to eliminate it as a regulating variable. This means oil is constantly flowing through the cooler during testing, and these tests showed a 65 F oil temperature drop. This massive drop shows the cooling capabilities of this GTO oil cooler kit. Just like all of Mishimoto's GTO parts, this kit comes with the Mishimoto Lifetime Warranty to make sure your oil temperatures are always on point. High-performance engine oil cooler designed to regulate oil temperature and protect critical engine components. Efficient heat dissipation improves durability, maintains lubrication, and ensures reliable performance. 2004 Pontiac GTO Base 5.7 Liter 4L60-E, 2004 Pontiac GTO Base 5.7 Liter T56, 2005-2006 Pontiac GTO Base 6.0 Liter 4L65-E, 2005-2006 Pontiac GTO Base 6.0 Liter T56

• Mishimoto In-Line Oil Thermostat maintains optimum 185F oil temperature
• Reduces oil temperatures by 65F (without in-line thermostat installed)
• Minimal pressure drop

Enhance your Pontiac GTO's engine reliability with the Mishimoto 04-06 Pontiac GTO Thermostatic Oil Cooler Kit. Designed specifically for models equipped with 5.7L and 6.0L engines, this kit ensures optimal oil temperatures, promoting engine longevity and consistent performance. The high-capacity 25-row stacked-plate cooler provides efficient heat dissipation, significantly reducing oil temperatures by up to 65°F during operation, which helps maintain proper lubrication and prevents overheating under demanding driving conditions. The cooler's robust construction guarantees durability and effective thermal management, even during intense driving sessions. The kit includes a specially designed oil line adapter that seamlessly attaches to the oil filter housing, allowing for the secure connection of Mishimoto’s stainless steel -AN lines. Due to space constraints, a thermostatic sandwich plate was not used; instead, a compact inline oil thermostat is mounted under the headlight with a custom-fit bracket. This thermostat maintains a steady oil temperature of around 185°F, ensuring your engine runs within the optimal thermal range. During testing, the oil flow remained continuous without the thermostat, demonstrating the cooler's impressive capacity to lower oil temperature and improve overall engine health. Whether you're racing or daily driving, this oil cooler kit provides peace of mind with its proven cooling performance and Mishimoto’s lifetime warranty. It is an essential upgrade for any performance-focused Pontiac GTO owner seeking to safeguard their engine and maximize reliability.
