Spark plug Champion or OEM BMW

I bought my 2019 330i in 2022. It was a lease return. While basic maintenance items are a lot more than, let’s say, a Toyota, it has been far from a money pit. I have put 50k miles on it in the three years I’ve had it, and had nothing out of the ordinary go wrong. Spark plugs, brake pads, air filters, tires, oil changes, that’s it.

The proper champion plug is the "QL77JC4" gapped at .030".

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.

I just got a new to me 2016 f150 with 120k. Did air filter, cabin filter, spark plugs (had a misfire) and boots and oil change. I used champion plugs but most reccomend OEM. Got a wix air filter and a fram oil filter. I used full synthetic 5W-20 Valvoline R&P oil. Use rock auto for parts if possible.

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.

Some of my best vehicle purchases have been trucks with "misfires" or "engine issues" and almost all of those have had goddamn champion plugs in them, or a champion distributor.

But let this be a lesson never use champion plugs again

Champion are the only plugs I’ve had the ceramic crack on, so no more Champion for me.

My service center guys installed Champion plug instead of Bosch on my turbocharged Altroz. Company user manual clearly says to use Bosch in TC. My car's economy has dropped significantly...and I'm just frustrated.
