E30 Large Fin Diff Cover: New
The E30 differential cover is designed for Motorsport applications that demand the utmost in performance. Extra large cooling fins dissipate internal heat to reduce the breakdown of internal gear oil. By lowering the internal temperature, the differential can work harder with less wear. The E30 differential cover is the perfect complement to one of our rebuilt or custom differentials. Don't forget to use Red Line oils when upgrading your differential! Fits E30 6 cylinder applications and E30 M3.
