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 2003-2006 Nissan 350Z, we've bundled together our aluminum radiator, silicone radiator hose kit, performance aluminum fan shroud, racing thermostat, and thermostatic oil cooler kit.

As the stand-out component, our aluminum radiator features full aluminum construction with durable TIG-welded end tanks. In addition, this radiator features a large 1.42" 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.

For added cooling performance, our Ultimate Bundle also includes our Performance Aluminum Fan Shroud Kit. This unit features two high-flow electric fans capable of rapid heat reduction. For ease of installation, our fan shroud kit includes factory plugs and is a complete bolt-in fan solution. The Mishimoto thermostat has a lower activation temperature (154.4°F) than the factory thermostat (172.4°F). The lower activation temperature allows coolant to flow through the engine earlier, reducing the risk of overheating in hot environments.

Our Ultimate Bundle also addresses oil temperatures. This bundle includes our direct-fit thermostatic oil cooler kit for the Z33. This complete bolt-on oil cooling solution is proven to reduce temperatures by 25+°F. Our kit includes a large 19-row stacked plate cooler, direct fit brackets, pre-made oil lines, and a thermostatic sandwich plate for complete oil temperature control.

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.
