Product Details

The Mishimoto MMRAD-E46-323 is a high-performance aluminum radiator engineered specifically for 1999-2006 BMW E46 Non-M vehicles. This direct-fit upgrade delivers significantly improved cooling efficiency over the factory radiator, reducing coolant temperatures by up to 19°F (10.5°C) to help protect your engine during spirited driving or hot weather conditions.

Key Features:

  • 40mm, 2-row fully brazed aluminum core for maximum heat dissipation
  • TIG-welded aluminum end tanks for superior strength and durability
  • Direct bolt-in fitment requiring no modifications
  • Professional installation possible in approximately one hour
  • Proven temperature reduction of 19°F compared to OEM radiator
  • Lightweight aluminum construction reduces front-end weight

This radiator is ideal for BMW E46 owners seeking improved cooling performance for daily driving, track use, or modified engines. The all-aluminum construction provides excellent heat transfer while resisting corrosion better than stock plastic-tanked radiators. Mishimoto backs this radiator with their lifetime warranty for complete peace of mind.
