One of the spark plugs used with the civilian ignition conversions. Excellent quality, less prone to fouling than the Bosch plugs. We prefer this plug for the Unimog Ignition Conversions. Our preference for the Pinzgauer would be the BPR6ES.
Be sure to remove the "Nub" from the ends of these plugs if you are using the EI "Beru" style of spark plug wires.
