M156 Weistec Spark Plugs
Does anyone have more information on these spark plugs?
I know for a time they were selling plugs made by Brisk. After a little research, I have found a couple instances of their plugs failing in the M156.
The porcelain breaks loose from inside of the spark plug which is a concerning failure. I have this seen this on several OEM spark plugs on direct injected Mercedes Benz engines, but never on an M156. I found multiple instances of their plugs failing in this same way on the M157, but the OEM plugs fail in the same fashion.
