2015+ BMW M3 - M4 (F80 M3 | F82/F83 M4)
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.

Garrett Powermax™ direct fit performance air-to-liquid intercooler for the 2015+ BMW M3 and M4 boasts a 47% larger core with dual pass coolant flow to help reduce intake manifold temperatures by an average of 10 °F. Optimized end tanks improve air flow through the core.
An average increase of 12.4 horsepower and 4.9 lb-ft of torque were measured during back to back dyno pulls. This direct fit performance intercooler installs in 1.5 hours and reuses the stock bolts, hoses, and clamps.

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
OBD II Data
- 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
