High Efficiency Tripleflow Core Highlights

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) LEARN MORE

Optima Core Highlights

Extreme style copper core with 1/2" tubes on 5/16" centers. Offers 40% more heat transfer points. The most efficient core on the market when combined with increased air-flow and our Tripleflow option (note: In almost all cases, we will not sell the Optima core without the Tripleflow option. Our Tripleflow option requires that inlet and outlet be on opposite sides and must use auxillary tranny cooler for automatic transmission vehicles). LEARN MORE
