NGK Laser iridium. Buy from a real distributor like Rock Auto.
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.
I went with NGK plugs and coil packs at about 95k miles on my 2.5. I'm about 40k miles later and. It's still running great.
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.
On a 2.0T it's pretty darn easy. The Gen 3+ engines have the bolted down coil packs with the ground wires/nuts, which can be tricky. You might need to counter hold with a thin style wrench, but other than that it's fairly straight forwards. I'd be sure to use only legit plugs from reputable sellers--there are a surprising number of counterfeit NGK (and Bosch and Denso) plugs out there. Fake plugs can cause more than just pesky misfires too, they can break off in-chamber and cause catastrophic engine and/or turbo charger damage. Not worth it to save a few bucks and potentially end up in ruin. NGK are the OE most of the time so getting the Laser Platinum or Ruthenium HX are recommended. Whether or not you want to replace the coils is up to you. I'd say it's too new for that and if you don't have a ton of miles on it, probably not necessary. The spark plug interval on these engines is comically short too--I'm not sure why VAG does that but they do that across the board on their engines. The original plugs will go for 2x the specified interval without any issue at all. If you are not super high miles and you pull them out and see "they look just fine"? Don't be surprised because they probably *will* be just fine. That said if you're still under warranty (base or extended), change them as specified.
yup those are done.
the center electode is worn flat and the gap is way too wide.
just replace them. make sure yu use the specified NGK or Denso Iridium plugs.
Yes, they have a lot of buildup and deposits. Make sure you get that exact spark plug again same brand everything don't put anything other than the NGK that originally came with
They are 2 hot for the engine , (the orange burns ) try colder plugs like heat range 8 NGK (SILZKR8E8G97080) are heat range 8 . The ones you have are 92422 are heat range 6 they are 2 hot . Same plugs fit my 2013 Veloster turbo fit your car .
I changed the plugs on my 2017 raptor recently with NGK iridium plugs. The punchline is that the truck started backfiring when I pushed it. I ended up putting Motorcraft plugs in and it cleared up.
It has 90k miles and we've been having issues with spark plugs. 3 months ago we replaced them after a cylinder 2 misfire. About a month ago same thing. Both times they looked terrible. Diode was all corroded and the threads had oil on them. Last night on my way to work cylinder 2 misfire came back. Anyway, I always use iridium ngk plugs as thats what's recommended but they are getting expensive having to buy them every month or 2.
