Garrett direct fit performance intercoolers are engineered for increased vehicle performance while maintaining OEM fitment. Advanced CFD combined with bar and plate core technology results in lower intake temperatures that increase heat saturation point.


• Supports up to 980hp • 47% larger core than stock • Installs in stock location • Cast aluminum end tanks • Air-to-liquid design • Bar-and-plate construction

Two Color Options

  • Flat black finish 888883-6002 
  • Raw aluminum 888883-6001 

Performance Dyno Testing

We performed a vehicle dyno test to gather data comparing the OE to Garrett intercooler. Multiple back to back dyno pulls measure intercooler effectiveness by comparing horsepower output, inlet and outlet temps, OBD II data.

  • Engine gains 12.4 horsepower and 4.9 lb-ft of torque on average after heat soak (10th pull)
  • Engine gains 18.7 horsepower and 6.4 lb-ft of torque at the 15th pull


  • After heat soak, charge air flow rate and pressure increase
  • ~2 lb/min higher charge air flow rate after 10th pull
  • ~1.5 psi higher charge air pressure after the 10th run


Thermal Data

  • Garrett intercooler outlet temp is ~5 °F lower each run before heat soak
  • OE intercooler has 90% instantaneous effectiveness
  • Garrett intercooler has 92% instantaneous effectiveness
  • Garrett intercooler outlet temperature is ~10 °F lower after heat soak
  • At heat soak, outlet temperature drops by 10 °F

CFD Optimization

  • CFD optimized design allows Garrett engineers to improve flow distribution through the end tanks
  • The charge air flow shown in the chart depicts air flow per passage
  • The variation is ~7% from the mean flow

Heat Transfer Modeling

  • CFD also helps improve thermal performance
