Radiator Cap - High Pressure AW/SW

$ 15.95

This is a replacement, 16psi high-pressure radiator cap.  Stock caps are 13psi, so the increased pressure will help raise the boiling point of the coolant, allowing more headroom on performance engines or engines that see heavy use.

The only drawback is the increased strain on the cooling system components, which is a negligible effect on a healthy, good-condition radiator and hoses. Caution on use with old, rusty cooling systems, but we would not recommend driving, let alone racing, a car with a neglected cooling system. 


Fits all AW11 and SW20 chassis. "Type A" Cap
