In another life I worked for Long Manufacturing and we designed and prototyped and made heat exchangers for everything from power steering, rads, intercoolers, Daytona 500 race cars, you name it. Also white-label manufactured many of the household brands B&M etc. etc. etc.
I worked in the R&D dept. and man, there are so many variables designing a heat exchanger bigger is not always better. It's almost rocket science. It was never as simple as taking Ambient and Surface Area and Target Temp. Fluid speeds (air and water) and all kinds of stuff influences the final design. Bigger can even perform worse.
Short story it's complicated and every time I see specs like FINS and SURFACE AREA and DEPTH compared to stock I usually just roll my eyes. They are also non-fat and zero added sugars!! BUY NOW.
Sure some will work but as other's have said do the math and then TEST IT that's all we did in R&D over and over every day.
Anyhow I myself did buy a PLM secondary one as I saw data here on mbworld that it does help with back to back runs. BUT that might also be confused with the fact that most people that get the larger secondary cooler PROBABLY also do the always-on mod at the same time. https://mbworld.org/forums/w212-amg/...w212-m157.html

i think most guys will prefer the MB OEM plugs because they can more easily be indexed than these NGK's but if you want 2 step colder plugs then these NGK 1555's have worked well for me if you can find a skilled enough MB expert mechanic to index them propertly for you

I and several others actually have those NGK 1555 plugs on our e63/m157s and they are definitely challenging to index properly since they're a tad smaller than the MB OEM plugs. My indy who's a former MB master tech has a technique to properly index these NGK's without using washers but you have to plan to buy extra plugs since the threads can vary slightly which impacts if that specific plug can be indexed and torqued properly. i have an ams 100 octane tune and never had a mis-fire with these plugs, but another friend of mine has the same tune with MB OEM plugs and no mis-fires either.

We had factory one step colder Mb plugs on an m157 that went 10.03 @144 in the 1/4.
The indexing comes down to where the threads start. The factory plug it starts in the same area on all of them. We used to run NGKs, but we would buy 100 of them, and sort them out looking for the proper thread position. But you do what you want, not trying to help you are anytime. Guessing you don’t more sets of m278/157 spark plugs them me, I am sure!!!! It’s just not worth it using NGK over factory plugs. How fast is your car?

So I am guessing he’s removed a cylinder head to see which way the plug faces? Guessing he thinks torquing them more than 23nm moves the indexing? Oh I think it’s so funny, when guys say they were an MB master tech. I hear that all the time

How hard is to get them indexed. I've never heard of this before. I am new to this platform. So you can't just install these as they are??

Please just buy some factory plugs. I’ve installed over 25 sets of m278/157 plugs. Trust me do not use the NGKs
