A clutched supercharger pulley for the Mercedes M112K supercharged V6 — fitting the C32 AMG, SLK32 AMG, and Chrysler Crossfire SRT-6. Available in 72mm, 68mm, 65mm, and 63mm sizes, it increases boost and supercharger RPM for meaningful rear-wheel power and torque gains while reducing rotational mass. A supporting tune is required.
