Mishimoto PWM electric fan controller in black. Instead of simple on/off switching, it pulse-width modulates the fan to vary speed with coolant temperature — ramping airflow up smoothly as temps climb for quieter operation and steadier cooling. Universal fitment with the included harness and temperature sensor.
