DINAN HIGH PERFORMANCE INTERCOOLER - 2007-2012 BMW 3-SERIES N54 or N55 E-Series

Greater power gains are achieved with a larger high-performance intercooler. The Dinan intercooler provides a 93% increase in total volume, substantially reducing the pressure drop by 0.7 psi, as well as providing more efficient heat exchange. "Cool down" time is also reduced enabling the cars to produce full power under varying driving conditions such as stop and go traffic. The system has been engineered as a direct replacement for the stock unit, requiring only minor modifications for a clean, factory-like installation. The intercooler also features larger connector tubing and custom shrouding for maximum efficiency. Used in conjunction with Stage 2 Performance Engine Software the intercooler produces an additional 5 horsepower as well as more consistent performance under varying driving conditions. The improved thermal efficiency will also enhance turbocharger reliability. The intercooler may also be used in conjunction with the Dinan oil cooler and Stage 3 Engine Software with increased boost pressure to take advantage of the improved intercooler efficiency.

Dyno results for Stage 3 engine software Dinan Intercooler, Dinan Oil Cooler and Free Flow Exhaust result in peak power of 398 HP @ 5700 RPM and 429 TRQ @ 4300 RPM.
