Spark plug Bosch or OEM BMW

I did absolutely nothing apart of spark plugs and oil change . I had E90, 188k km, 330d until it meet it's end when I crash it to railguards. it never showed me any lights or anything so I would say around 60-80$ tops.

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...

August 28 2024 : Spark plug change Bosch 70,588

I almost went 200000 km on my bmw between spark plug changes, and the motor runs so much better after. My fuel economy almost doubled, and performance was a night and day difference

I run more or less the same motor (2.1liter-276 Schrick-10.5CR), and I'm using stock Bosch spark plugs.

I did my spark plugs on my 335i f30 and I can say one thing. $400 for labor on spark plugs is treason. Shit should take those "experienced" mechanics maybe an hour.

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.

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.

NEVER USE THE DEALER FOR REPAIR WORK!

I dug factory installed spark plugs out of my recently departed E90... they looked like something from the stone age. 19 year old car, and from what I could tell, never had the plugs changes.
