Mishimoto 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% increase in coolant surface area, a 15% increase in air surface area, and a 25% 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% 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.

Mishimoto performance radiators are designed and engineered to maximize cooling efficiency, boost engine functions, and, most of all, protect your engine from overheating. Many stock radiators can't handle the additional heat that comes higher horsepower levels. So, swap out your stock radiator for an all-aluminum Mishimoto.

Key features and benefits of Mishimoto performance radiators include:
• Available for universal and exact fit applications (no cutting or modifications required)
• All-aluminum construction for optimal heat dissipation, improved strength, and reliability
• Increased cooling capacity due to their massive core size
• 100 percent brazed aluminum core for minimal distortion, low stress, and clean joints
• Available in various sizes with 2-row or 3-row cores
• TIG-welded for clean, strong welds and increased durability
• Magnetic drain plugs capture metallic debris or fragments
• Included high-pressure 1.3 bar cap raises the coolant boiling point for greater safety and efficiency
• Automatic transmission and accessory coolers included where applicable
