Expert's advice:
“Upgrade the cooling of your E90 BMW. The Mishimoto Intercooler for E90 models with the N54/N55 engine increases the core volume by 22% without requiring modifications to your vehicle.
The cooler is constructed with cast end tanks and precision CNC-machined aluminum quick disconnects for use with the factory intercooler piping. The intercooler reduces intake temperatures by 19.45°C (35°F) and provides an increase of 20+ hp while retaining factory boost pressure across the core.”
