Dinan High Performance Heat Exchanger for BMW F80 M3 F82 F83 M4

Dinan High Performance Heat Exchanger for BMW F80 M3 F82 F83 M4


The stock system cools the intake charge by using a water-to-air intercooler, an expensive piece to engineer. The cooling circuit for the water that feeds the intercooler uses a primary cooler (heat exchanger) and a smaller secondary cooler in front of the passenger side wheel. Through rigorous testing of all 3 of those components and multiple combinations therein it was discovered that the most effective performance per dollar solution was replacing the heat exchanger with a larger unit. 

Benefits of the Dinan High Performance Heat Exchanger for the F8x M3/M4:

  • Consistent +10 HP / +20 ft-lb of torque on the stock engine tune. Additional gains realized when used in conjunction with the Stage 3 DINANTRONICS Performance Tuner. 
  • 60% more core volume & 19% more face area than stock
  • 40mm thick Dinan cooler vs. 24mm thick stock cooler
  • 9° average water termperature reduction to the intercooler across the RPM range. Colder water improves intercooler efficiency and allows the intake air to be cooled by an additional 6° average 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
