Owner reviews for spark plug

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

Ive been running eBay denso plugs for 4 plug changes. You need to read reviews and look at the packaging to make sure they're not counterfeit. They've lasted me and performed exactly as they should.

Also, make sure you go with the HKS plugs, they will be the longest lasting plugs, followed by NGK (yes, I know that HKS is owned by NGK).

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.

Lol 560 for 4 piece spark plug? That plug better be made of gold even laser iridium also doesn't cost that high. Good ngk iridium cost no more or less than 300. That syn 3k for 300 can get a far better brand n enhanced thermal and oxidative stability grade.

They look good but if the vehicle has 83k, they were replaced before, Denso is OE on toyota and Autolite are shit plugs so no way they were in since the car was brand new.

Yea,get some ngk’s or denso,autolite plugs are garbage.

The plugs it had in it (autolite) didnt look great.
