Dinan 14-16 BMW 228i High Performance Dual Core Intercooler

Greater power gains are achieved with a larger high-performance intercooler. The Dinan dual core intercooler provides a 240% increase in face area along with an equally impressive increase in volume, substantially reducing the pressure drop to 0.8 psi, as well as providing for more efficient heat exchange and more consistent output power. Dinan's unique dual-core design allows 2 separate cores to be working in conjunction with one another at all times. This doubling of resources is directly responsible for a 60% improvement in the delta from charge air temperature to ambient temperature (see diagrams). "Cool down" time is also reduced, enabling the cars to produce full power under varying driving conditions such as stop and go traffic. This leaves the chances of being susceptible to heat soak nearly a thing of the past. Air-To-Air - F22/F30/F31/F32/F34/F36 Not compatible with vehicles equipped with Active Cruise Control or the F23 / F33 chassis' (convertibles).
