Restore your cooling system with the Mishimoto Ultimate Bundle. The Mishimoto Ultimate Bundle includes high-quality upgraded cooling components to replace items we've found to be the most failure-prone. For the 2015-2017 Ford Mustang V8, we've bundled together our aluminum radiator, silicone upper radiator hose, silicone lower radiator hose, silicone ancillary hose kit, racing thermostat, aluminum coolant expansion tank, and oil cooler kit .As the stand-out component, our aluminum radiator features full aluminum construction with durable TIG-welded end tanks. This radiator is a three-row unit with a 52mm thick brazed aluminum core. We've included our incredibly robust silicone radiator hose kits for the V8 Mustang to supplement this radiator upgrade. This includes the upper radiator hose, lower radiator hose, and all ancillary coolant hoses. Mishimoto silicone hoses are constructed from high-grade 4-ply silicone with heat-resistant embedded fibers for superior heat and pressure tolerance. For maintaining low fluid temperatures, we've included our Ford Mustang Racing Thermostat. The Mishimoto thermostat has a lower activation temperature (160F) compared to the factory thermostat (190F). Distinguishing itself from the Essentials Bundle, this Mishimoto Ultimate Bundle includes two additional items for long-term vehicle protection. First, our 100-percent aluminum coolant expansion tank, a direct-fit replacement for the plastic factory unit. The robust, TIG-welded construction ensures maximum durability during repeated temperature transitions. To protect your oil from overheating, this kit includes our highly efficient direct-fit thermostatic oil cooler kit for the 5.0L. Our kit positions the included bar-and-plate cooler in the upper front grille for maximum airflow and cooling efficiency. Time to re-habilitate your Ford Mustang's cooling system with the Mishimoto Ultimate Bundle. As with all our products, this bundle includes the signature Mishimoto Lifetime Warranty.
