Keep your E46 M3 cool with the Mishimoto Performance Aluminium Fan Shroud Kit! This unique electric fan shroud setup completely eliminates the stock, failure-prone mechanical fan. The fan shroud mounts directly to both stock and Mishimoto radiators and includes a 16in high-flow electric fan that produces over 1850 cfm of airflow. Our in-house Dynojet testing has shown a 5 whp gain from 6500-7500 rpm and 1-2 whp gains over a majority of the power band after removing the factory clutch fan. Optionally, this kit can include an adjustable fan controller and wiring kit, which will provide the user with total control over coolant temperatures. The Mishimoto BMW E46 Fan Shroud Kit includes a removal tool for the clutch fan as well as all hardware required for installation. This fan shroud has a brushed finish that provides a subtle accent for your engine bay. As with all our products, this fan shroud kit includes the Mishimoto Lifetime Warranty, ensuring superior Products quality and craftsmanship.
