By re-routing the coolant through the core three times the coolant travels farther in the temperature reducing air-flow and the additional time spent dropping temperature results in amazing heat transfer rates. Copper/brass construction to ensure dependability. (note: Tripleflow option requires that inlet and outlet be on opposite sides and must use auxillary tranny cooler for automatic transmission vehicles)
