Zionsville
Autosport 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
Zionsville Autosport's radiators.

Additionally, Zionsville Autosport's 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, Zionsville Autosport's 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.
Lifetime Warranty!
Zionsville Autosport guarantees our radiators for life to the
original purchaser. Purchaser must provide proof of BMW coolant
use at first installation and once every two years thereafter.
