Radiator, C&R Aluminum - E46 M3

The BimmerWorld View: not all aluminum radiators are created equal. This radiator uses a PWR core that is more efficient and cools better than larger cores. Not only is the smaller core lighter than other aluminum radiators but less fluid is also a weight savings! There is no magic trick - PWR is simply a higher quality, more precise, better manufactured core than anything else on the market. PWR Is the cooler supplier for NASCAR, F1, WRC, BMW GT3 and GT4, and other top-tier motorsport programs.

Ultra-premium, race-quality radiator keeps your engine cool for maximum power and longevity

Since partnering with C&R Racing in 2004 to produce radiators for our pro racing program, they have been the sole radiator supplier for every BimmerWorld Racing car built since. With years of experience as the leading U.S. manufacturer of racing performance parts, it's no surprise that C&R products are able to keep our engine investments running strong even in the most demanding altitudes, heat, and airflow conditions.

We've proudly partnered with C&R Racing to bring this same level of quality and performance to your street, track, or race car, all with a direct fit for easy installation. Fully brazed cores contain no epoxy and are built to specifications that maximize cooling efficiency. All aluminum radiators are not the same - not even close... Anything labeled C&R will be a true performance part, not a sheep in wolf's clothing.

This new design is lighter than the outgoing 56 mm C&R radiators and feature the latest 42mm core design from PWR for improved efficiency and cooling power.  And beyond the reduced part weight, filled weight is a stunning 11# lighter than our 56mm radiator - weight savings in front of the front axle, where it is critical! 

Our E46 M3 radiator fits using the original plastic shrouding and mounting points but trimming may be needed to achieve the perfect fit and seal. The original hoses and plastic connectors can be used also.
