Because this pulley is so much larger than the original (70%), special care will need to be taken so that it does not interfere with other components on the engine - power steering lines, oil cooler lines, coolant hoses, etc. This pulley is strictly for race/track cars only, due to the size of the alternator pulley the proper voltage cannot be maintained at low RPM. For the stock M3 alternator only. This pulley must be used with the Turner Power Pulley kit Show more
