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.

Yeah they’re still Brisk. Discussed here with Brisk part numbers etc https://mbworld.org/forums/c63-amg-w...ml#post7404823
I’ve run at least 6 sets and never had a problem with any of them.

I just received an E mail from their sales department stating they are now an NGK spark plug due to the issues they were having with Brisk.
I ordered a set and will compare them with the stock plug. I'm assuming it is just a colder plug then stock.

I concur! This is with Wiestec's canned Stage 2 tune and 93 Octane Chevron fuel from a fairly new fuel station that I regularly get gas for all my hot rods. No signs of speckling or detonation on any of the plugs. But hey, don't panic. Maybe it's just due to the added cylinder pressure of the S/C cars. I know another C63 owner that ran the brisk plugs N/A and he never had a problem.

It happens to the OEM plugs on the newer DI motors, I've seen it on several 274's and occasionally in the 276/278 cars. Never seen one on a 156 but they don't come in nearly as much as they are falling out of warranty and going to Indy shops more.

Exactly what ItalianJoe1 said.
Here is Weistec's email:
Hello!
We do not use the Brisk plugs any longer for this reason. The new plug we use is an NGK unit, and we have not seen any failures as of yet.

If you are running a 67mm pulley you will be fine but if your running a 60mm pulley NGK plugs will NOT be cold enough and you might get issues
with 60mm and race fuel i get best performance from Brisk plugs
