Bigger is better. Dinan high performance heat exchangers, with their larger stature, elicit increased efficiency, plus twice the effectiveness of your stock setup. Impressive power gains and a wider power band, along with astounding cooling characteristics, nearly guarantee that "heat soak" is a thing of the past.

Benefits of the Dinan high performance heat exchangers:
• Consistent +10 hp/+20 lbs.-ft. of torque on the stock engine tune. Additional gains realized when used in conjunction with the Stage 3 DinanTronics performance tuner.
• 60 percent more core volume and 19 percent more face area than stock
• 40mm thick Dinan cooler vs. 24mm thick stock cooler
• An average of 9 degrees water temperature reduction to the intercooler across the rpm range. Colder water improves intercooler efficiency and allows the intake air to be cooled on average by an additional 6 degrees across the rpm range compared to stock.
• Significant reduction in tendency to heat soak
• Rubber-mounted for vibration isolation
• Track-tested to ensure consistent performance under extreme conditions
