Description
The Mishimoto Performance Aluminum Fan Shroud Kit (MMFS-E46-01K) is purpose-built for the 2001-2006 BMW E46 M3, replacing the notoriously failure-prone factory mechanical clutch fan with a brushed aluminum shroud and a 16-inch high-flow electric fan rated at over 1850 cfm of airflow. It’s a direct-fit cooling upgrade engineered specifically around the S54-powered E46 chassis, not a generic universal fan kit.
By eliminating the parasitic drag of the stock clutch fan, this Mishimoto cooling upgrade frees up measurable power: in-house Dynojet testing recorded a 5 whp gain between 6500-7500 rpm and 1-2 whp gains across a majority of the power band after the factory fan was removed. The 16-inch electric fan mounts in an offset position on the aluminum shroud, which clears space for popular supercharger kits, and the shroud is compatible with both the stock radiator and Mishimoto’s own E46 M3 radiator. For drivers who want more precise thermal management, the kit is available with an optional adjustable fan controller and wiring kit that gives total control over coolant temperatures, including at idle.
Vehicle Applications
