BMW Radiators

We sell only OE supplier or approved aftermarket upgrade radiators for your BMW. It seems BMW took some shortcuts when it came to radiator design and used weak materials like plastic for critical connection points. If you are tracking older models like E30, E36, or E46, you probably are well aware of these issues. As these cars age, the plastic pieces become more brittle and failure prone. The solution is to replace with upgraded radiators that perform as upgrades for the original, failure prone radiator to avoid being left on the side of the road or, worse yet, the track.

E46 M3 Fluidyne / Turner Aluminum Radiator Upgrade
Turner Motorsport - Corporate Logo
Part#: FHP13X-01E46M
In Stock

+25% capacity

  • Triple-row core (vs double row)
  • Better cooling without increasing overall dimensions
  • All-aluminum construction

This is the new E46 M3 aluminum radiator that we collaborated with FLUIDYNE on. We're 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.

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. 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.

The stock radiator has an aluminum core but with plastic end-tanks and hose connections that become brittle and can leak or crack. You may not even realize your radiator neck is cracked until it's too late and you're stranded on the side of the freeway or unable to continue with your track day. An all-aluminum design does not suffer the defects of similar plastic construction. FLUIDYNE quality is what sets them apart from every other manufacturer. 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.

Some modifications may be needed to to fit this radiator.
