Spark plug OEM BMW or OEM Honda

It is, I have a 2020 330xi with 80k miles. It runs like a champ. Make sure you change out spark plugs. Most people don't. NGK's come with the car.

The tools aren’t expensive. Yes I use dielectric grease but not anti sieze on the threads (only because BMW orders us not to). Easy job for most cars.

Eu tenho dois Honda Jazz. As manutenções são super baratas e os carros nunca avariam. Melhores carros de sempre... Até chegar à altura de trocar as velas... Sim, são a 40 euros cada. Preço normal.

Using the muzzler has stopped mine needing the spark plugs changed / having a cylinder go out every 6 weeks.

use BMW OEM plugs from the dealer. Yes the are expensive but I have never had a problem with misfires and I've put over 100,000 miles on my current E36 and over 150,000 on my first. While they are suppose to work and be interchangeable according to the manufacturer the NKG you buy aftermarket are supposedly different than what you get from BMW

I had similar problems with mine until I tried stock F80 M3 plugs. Mfg #12120039634KT1. Mine was 07 N54 FBO.

I just completed my first spark plug change on my G20 330 at 40k miles. Three of them especially Cylinder 1 came out "wet" and I'm unsure if it's oil.

If you are willing to put some money into it before resorting to drastic measures, try replacing all 6 of your spark plugs and ignition coils. Might help in your case, or it might not.

Cylinders 1-3 were misfiring. They couldn't get the spark plug out of cylinder 3 because the other dealership had over tightened it. They had to get a special tool to remove it. The tool BROKE because apparently it was so overtightened and mis-threaded. They finally got it out yesterday and sent the cylinder to the machine shop to get the head off. I just got word that there is a hole in the piston and the valve head is completely gone. They are saying now that it has nothing to do with the spark plug being overtightened. He asked about driving through water, and road conditions. It was a dry day. Not an issue. They said I need a new motor at this point.
