Restore and enhance 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 2007-2009 Nissan 350Z, we've bundled together our aluminum radiator, silicone radiator hose kit, and racing thermostat.As the stand-out component, our aluminum radiator features full aluminum construction with durable TIG-welded end tanks. In addition, this radiator features a thick 2-row core providing a substantial improvement in cooling efficiency. To supplement our robust radiator, we've included our incredibly durable silicone radiator hose kit. Mishimoto silicone hoses are constructed from high-grade 4-ply silicone with heat-resistant embedded fibers for superior heat and pressure tolerance. To help keep oil temps in check, we've also included our thermostatic performance oil cooler. This 19-row stacked plate cooler is proven to reduce oil temperatures by up to 25F.Rounding out our bundle is the Mishimoto Racing Thermostat. The Mishimoto thermostat has a lower activation temperature (154.4F) than the factory thermostat (172.4F). The lower activation temperature allows coolant to flow through the engine earlier, reducing the risk of overheating in hot environments. Time to re-habilitate the cooling system of your Z with the Mishimoto Ultimate Bundle. As with all our products, this bundle includes the signature Mishimoto Lifetime Warranty.
