Description
The Mishimoto Performance Fan Shroud Kit (MMFS-E46-99) is a direct-fit electric fan and shroud assembly built to replace the failure-prone stock mechanical fan on BMW E46 chassis vehicles. At the heart of this Cooling upgrade is a 16-inch high-flow electric fan rated to move over 1850 cfm of airflow, giving E46 owners a fan setup that outperforms the factory electric fan found on manual transmission models.
Beyond raw airflow, this Mishimoto fan shroud kit is engineered to bolt directly to the stock or Mishimoto E46 Performance Aluminum Radiator on both manual and automatic transmission cars, and it works with either the stock coolant expansion tank or a Mishimoto aluminum expansion tank. Its slim profile keeps maximum depth to just 3in, freeing up valuable engine bay space compared to the factory mechanical fan setup, while the Black Powder-Coat finish on the steel shroud blends in cleanly under the hood. For drivers who want more command over their cooling system, the kit can optionally be paired with a Mishimoto Adjustable Fan Controller Kit to dial in total control over coolant temperatures.
Vehicle Applications
This fan shroud kit is built for the BMW E46 platform and related chassis, covering the 1999–2001 323i, 1999 323is, 2000 323Ci, 1999–2000 328i, 1999 328is, and 2000 328Ci, along with the 2001–2005 320i, 325i, 325xi, 330i, and 330xi.
