E36 & E46 Sport Fan Clutch | 323 325 328 330 M3 mad max *Note: THIS SOFTWARE TUNE COMESWhen you push your powerplant, thermodynamics pushes right back. The toll of high performance is higher heat load and many stock components begin to complain. This upgraded fan clutch increases viscous coupling of cooling fan blade speed to water pump speed, yielding increased airflow through the radiator for more efficient cooling. A simple, yet wonderful, thing.
