Spark plug OEM BMW or BRISK

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.

You get a better performance if you install a booster plug, DNA air filter and Brisk spark plugs. Great torque from 2000 rpm as a result.

I use a Brisk n17yc.

Get a Brisk spark plug. Worked for me

Been using the cheaper Brisk brand and never had an issue for 20k miles.

Right before i changed the map I also swapped spark plugs (brisk er12s). Since it started the rough vibrating, I’ve inspected spark plugs and coil packs, changed the coil pack grounding to a ground kit, cleaned the MAP sensor, and even tried throwing some liquimoly valve clean in it.

Brisk are fine. You have to check them about every 5,000 miles. And change out sooner than other brands.

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.

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.
