Stock is generally fine, however if your tracking or going through multiple heat cycles on your drives id recommend er12s from brisk. I run them and they havent skipped at beat. Intervals are shorter for changes.

Pros: havent skipped at beat
Cons: shorter change intervals
Part number: ER12S

It doesn't look eroded. It looks like the centre electrode tip has fallen off. That shouldn't happen. I usually only use Bosch or NGK plugs. I've never heard of Auto lite...

Pros: reliable

Your observation is correct.

Bosch is the original manufacturer. Buying from them will be cheaper. Mercedes genuine just means they take the Bosch part and slap their name on it to say "yes, this component is up to our standard".

Pros: cheaper, original manufacturer
Cons: Mercedes mark up price

Changed valve cover/gasket and installed new Bosch plugs and NGK boots.

Car had slightly higher rpms at cold startup but didn\u2019t think anything was wrong. After a few days engine started to misfire. I did some research and it sounded like I should use OEM plugs. I purchased Nissan plugs from the dealer and replaced the Bosch plugs. Misfire went away, but higher rpms at cold start persisted.

Pros: misfire went away
Cons: higher rpms at cold start
Mileage: 90000 km

I have a 21 xlt 4wd 2.7 and I do A LOT of driving for work. Recently crossed 80k miles and it started misfiring like crazy shortly after that and threw a code. Pulled the plugs and they were definitely fouled. I did some reading and saw most people change the plugs out around this interval so I went ahead and did it. EVERY auto part store near me only had 1 or 2 oem plugs and I couldn\u2019t really wait so I went ahead and got BOSCH iridium plugs. Well I\u2019m noticing when I get on it or go to speed up at higher RPMs/gears, I\u2019m getting what feels like stuttering or very minor misfires every now but it\u2019s not throwing any codes.

Cons: stuttering, minor misfires
Mileage: 128747 km

If it is the skyactive-x be aware that the owners manual advises spark plug replacement at 40k miles and the Mazda plugs are \u00a340 each. I put aftermarket Bosch plugs in and it ran very lumpy and had to replace with Mazda ones.

Cons: ran very lumpy
Vehicle: Mazda 3
