There has never been a better E46 M3 radiator upgrade than this! For an E46 M3 track or modded street car there should be no reason to ever go back to a stock plastic radiator or compromise on a cheap aluminum radiator. The latest FLUIDYNE is the best there is. Taking advantage of FLUIDYNE's new core design that packs much more surface area in a stock-sized core. Instead of the usual two rows of tubes, FLUIDYNE's all-aluminum radiator has three rows of tubes in a core no thicker than the stock radiator. This radiator also has 30% more rows than the stock radiator (55 vs 42). With greater surface area and more efficient use of air flow comes better cooling, especially in the most critical spot where the fins meet the tubes, as this is where most of the heat transfer happens. Where most other aluminum radiators use a thicker core, FLUIDYNE's new packaging solution performs better and fits better in the engine bay with better clearance to other components. A second benefit with this new core is that it minimizes added weight gain, helping to get the car as light - and as fast - as possible.
The goal was to make this as close to a "drop-in" replacement as possible. FLUIDYNE made this easy as this core is no larger than the stock radiator even though it has more capacity. We also had hangers designed to accommodate the factory oil cooler and fan shroud. Their radiators feature a high-tech CAB-brazed core construction instead of epoxy (which can leak). All tanks and brackets are TIG welded by hand in the USA. If you plan on owning your BMW for many years to come, or are using it in a situation where failure is NOT an option such as track or racing, then this should be your only option instead of the failure-prone stock radiators.
