E46 M3 Mishimoto Performance Radiator - MMRAD-E46-01 

The S54 is a simply awesome engine. It has smooth power delivery, individual throttle bodies, and an 8,000 rpm redline, but all of this performance can generate quite a bit of heat! As with any engine, keeping your engine temp under control is key to extending the life of your engine and keep it delivering maximum performance. Since the E46 M3 is such a capable car many of them see the rigors of the track, because of this Mishimoto has stepped it up a notch for this model and developed an even more capable radiator. The Mishimoto team of engineers developed an extremely dense core on this E46 M3 radiator, 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 BMW radiator is designed as a complete bolt-in fit, requiring no modification for fitment with the stock fan and shrouding. The Mishimoto BMW E46 M3 radiator 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. As with all Mishimoto products, the Mishimoto E46 M3 Performance Aluminum Radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
