Our radiators are constructed of materials that provide better heat dissipation. For example, PA66 GF30 is a glass reinforced nylon material used by Behr to manufacture O.E. radiator side tanks. UNS A93003 is the aluminum alloy we use in our radiators.



























































Thermal Conductivity





Specific Heat Capacity


PA66 GF30 0.22 - 0.5 W/m-K PA66 GF30 1.2 - 2.35 J/g °C
UNS A93003 193 W/m-K UNS A93003 0.893 J/g °C






Additionally, our radiators do not become weak or brittle due to constant temperature cycling. Glass reinforced nylon will eventually deteriorate resulting in a cracked or broken radiator neck. This failure has become more common due to the increased temperatures in the current generation of BMW engines. The normal operating temperature of a Double Vanos engine is around 110° C (230° F). Unfortunately, there is no way to tell what the real temperature is in the engine without special equipment. According to the BMW WDS, the instrument cluster temperature display will read normal between 75°-113° C (167°-235.4° F). Nylon just doesn't hold up under these conditions.





In short, our e46 radiator dissipates more heat and it won't break. And should it break, the original purchaser is covered by a lifetime guarantee... even if it's installed in a race car.





A note regarding the No Wiring Kit option: The factory auxiliary fan is operated by a variable speed control box mounted on the rear of the auxiliary fan. If one chooses to delete the auxiliary fan, the Spal fan can be operated by the auxiliary fan control box mounted in an alternative location. This simplifies wiring and eliminates the need to purchase a wiring kit from us. There are two drawbacks. The front end of the car must come apart in order to remove the auxiliary fan. Also, should the control box fail, it is not available as a separate item. It must be purchased with the auxiliary fan.
