2001-2007 WRX Ultimate

Restore your cooling system with the Mishimoto Ultimate Bundle. The Mishimoto Ultimate Bundle includes upgraded coolant components to replace items we've found to be failure-prone. For the 2001-2005 Subaru WRX, we've included our aluminum radiator, fan shroud, silicone radiator hose kit and ancillary hose kit, racing thermostat, aluminum expansion tank, performance oil cooler, and turbo blanket. Our aluminum radiator features full aluminum construction with durable TIG-welded end tanks. This radiator provides an increase in coolant capacity for superior heat dissipation and optimal cooling efficiency. To supplement our robust radiator, we've also included our performance fan shroud. In addition, we've included our incredibly durable silicone radiator hose kit and silicone ancillary hose kit. Mishimoto silicone hoses are constructed from high-grade 4-ply silicone with heat-resistant embedded fibers for superior heat and pressure tolerance. Finally, for maintaining low fluid temperatures, we've included our Subaru WRX Racing Thermostat. The Mishimoto thermostat has a lower activation temperature (154.4) compared to the factory thermostat (172.4). The lower activation temperature allows coolant to flow through the engine earlier, reducing the risk of overheating in hot environments. We've included our all-aluminum, fully TIG-welded coolant expansion tank within our Ultimate Bundle, providing maximum durability during repeated hot and cold transitions. Oil temperatures can begin to rise on vehicles driven aggressively or on track. Because of this, we've included our direct-fit oil cooler kit for the WRX, proven to drop oil temperatures by 20F. Rounding out our Ultimate Bundle is our Titanium Turbo Blanket, designed to reduce engine bay temperatures and maintain turbocharger efficiency. Time to re-habilitate the cooling system of your WRX with the Mishimoto Ultimate Bundle. As with all our products, this bundle includes the signature Mishimoto Lifetime Warranty.
