Editing Radiator (section)

===Triple Pass===
The triple pass radiators are only intended for motorsports and are '''not recommended for road use'''.  The reason being there is not enough coolant flow at idle (sitting in traffic) to force the coolant through three passes of the radiator.  Road users who have fitted triple-pass radiators have resulted in increased engine temps.  This advice holds for heavy trackday heros that drive their cars to/from circuit; the car is still liable to be stationary in traffic.
