The S54 is an incredible feat of engineering. Smooth power delivery, individual throttle bodies, and an 8,000 rpm redline makes for an unforgettable driving experience. As with any BMW, maintenance is key to extending the life of your vehicle and ensuring that you’re getting a driving experience rivaled by very few other vehicles on the road. As many of these vehicles see frequent track time, the team at Mishimoto felt a need to develop a performance aluminum radiator that would not only provide improved durability, but also deliver the efficiency needed for track driving. Our team of engineers developed an extremely dense core that provides a greater number of coolant tubes and a very dense fin composition. This allows for more heat-transfer contact points which results in greater heat exchange and improved efficiency. Additionally, this dense core provides a 32% increase in coolant surface area, a 15% increase in air surface area, and a 25% increase in coolant capacity. All these factors contribute to lower temperatures and greater heat rejection, ideal for those in warm climates and track use.
This radiator is designed as a complete bolt-in fit, requiring no modification for fitment with the stock fan and shrouding. Our end tanks are constructed from high-quality aluminum TIG-welded to a 100% brazed aluminum core. Not only does this aid in heat transfer, but it also provides the reliability needed for years of service. Pair this radiator with the Mishimoto BMW E46 M3 Silicone Radiator Hose Kit for added durability over your stock rubber hoses. This radiator is compatible with most aftermarket supercharger kits, providing the cooling power needed for power levels above stock. As with all our products, the Mishimoto E46 M3 Performance Aluminum Radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
