Mishimoto - misMMRAD-E46-01 - 01-06 BMW M3 3.2L Performance Aluminum Radiator

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-percent increase in coolant surface area, a 15-percent increase in air surface area, and a 25-percent increase in coolant capacity. All of these factors will 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-percent brazed aluminum core. Not only does this aid in heat transfer, but it provides the reliability needed for years of service. This radiator is also applicable 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. Aluminum radiator engineered for efficient heat dissipation and optimal engine cooling. Precision-fit design ensures easy installation, corrosion resistance, and reliable performance across varied driving conditions. 2001-2006 BMW M3 3.2 Liter S6S420G, 2001-2006 BMW M3 3.2 Liter S6S420G(SMG)

• Fits perfectly with stock clutch fan or Mishimoto electric fan shroud
• Fully brazed aluminum core with TIG-welded end tanks
• Precision designed

The Mishimoto Performance Aluminum Radiator is engineered for the 2001-2006 BMW M3 with the 3.2-liter engine, providing enhanced cooling efficiency and durability for street, warm-climate, and track driving. Its dense core increases coolant surface area by 32 percent, air surface area by 15 percent, and coolant capacity by 25 percent to support improved heat exchange and heat rejection.

Designed as a complete bolt-in fit, this radiator requires no modification for use with the stock fan and shrouding. It fits with the stock clutch fan or a Mishimoto electric fan shroud. The aluminum end tanks are TIG-welded to a fully brazed aluminum core, combining reliable construction with efficient heat transfer. The radiator is also applicable with most aftermarket supercharger kits and is covered by the Mishimoto Lifetime Warranty.
