Excellent quality at an affordable price. Filler neck is machined, not stamped, and water tanks are furnace brazed, not epoxied, eliminating two prime sources of leakage. The lightweight 1" tubes, arranged in two rows, offer outstanding cooling in race cars, off-road vehicles and street machines. Standard 1-1/2" inlets and 1-3/4" outlets have beaded hose fittings.
