Expert's advice:
We strongly recommend upgrading to a high-performance intercooler when your vehicle has been fitted with an ECU remap. An ECU tune typically increases boost pressure and ignition timing, which also raises intake air temperatures. The factory intercooler can quickly become a limiting factor under these conditions, leading to heat soak and reduced performance consistency.
An upgraded intercooler significantly improves charge-air cooling efficiency, resulting in lower intake temperatures and more stable engine performance. This allows the engine management system to safely run increased boost and more advanced ignition timing, helping to unlock the full potential of your remap while maintaining reliability in both spirited driving and demanding conditions.
The Mosselman High Performance stepped intercooler is designed to outperform the standard OEM unit by offering a substantially larger frontal surface area and increased internal volume. This improved core design enhances airflow and heat dissipation, ensuring more efficient cooling even under sustained load. Depending on the specific vehicle application, this intercooler can deliver performance gains of approximately 15 to 25 horsepower, along with improved throttle response and more consistent power delivery during repeated acceleration or high ambient temperatures.
