Solid Diode Board Mounting Studs - Set of 4; BMW 12 31 1 358 131 / EnDuraLast
Alternative Views:
Part #: BOALT-Mount131
Diode Board Metal Stud Mounts (x 4).
The rubber mounts are prone to damage from vibration and may cause the diode board to contact the engine case. Also with metal mounts the diode board is properly grounded without the need of external wire grounds. Incorrect grounding is a common cause of poor efficiency and reduced prevention of diode overheating.
