Restore and enhance your cooling system with the Mishimoto Essentials Bundle. The Mishimoto Essentials Bundle includes high-quality upgraded cooling components to replace items we've found to be the most failure-prone. For the 2001-2006 BMW M3, we've bundled together our aluminum radiator, silicone radiator hose kit, and performance aluminum fan shroud kit.As the stand-out comp onent, our aluminum radiator features full aluminum construction with durable TIG-welded end tanks. In addition, this radiator features a 25-percent increase in coolant capacity and a 32-percent increase in coolant surface area to provide optimal heat dissipation. Our radiator features precise CNC-machined quick disconnect fittings and includes a fan tool for removing the stock clutch fan. 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. Rounding out our Essentials Bundle is the Mishimoto Performance Aluminum Fan Shroud Kit. This kit allows for the removal of the failure-prone factory mechanical fan. During testing, we saw power gains of up to 5whp at high rpm. This kit includes everything needed to convert your M3 to an electric fan, including our adjustable fan controller kit. This controller provides complete control over idle and low-speed coolant temperatures. Time to re-habilitate the cooling system of your S54 with the Mishimoto Essentials Bundle. As with all our products, this bundle includes the signature Mishimoto Lifetime Warranty.
