Tegiwa Aluminium Alloy Radiator Bmw E46 M3 Race (62mm Thick)

  

The more you demand out of it, the higher temperatures will be, so you'd do well to invest in one of our aluminium radiators. As well as cooling your M3's engine more efficiently (up to twice as efficient), Tegiwa radiators are also noticeably lighter than OEM units, and fit perfectly with OEM brackets.
