Spark plug Autolite 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.
Pros: nothing out of ordinary
Cons: maintenance items pricey
Vehicle:
BMW
Mileage: 80467 km
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.
Pros: runs like a champ
Cons: spark plugs
Vehicle:
BMW
Mileage: 128748 km
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.
Pros: tools aren't expensive, easy job
Cons: BMW orders not to use anti-seize
Bought two auto light from autozone to fix a quick misfire. Used it for two years then took it out and saved it. Quick changed two with the auto light I had previously saved. And bought another one at autozone. 2 years later still running good. Gotten lazy to changed them out. But still running good in my 08.
Pros: long-lasting, reliable
Vehicle:
Ford
Just replaced all my spark plugs that were in for 83k miles. Autolites were in and replaced with Denso twin-tip.
Mileage: 133575 km
If it didn't misfire until you put plugs in it I would suspect the plugs are the cause.
Cons: misfire after plugs
Most Asian brands are pretty picky about spark plugs. You put Autolites in a 70s malaise-era Ford - not in a modern, sophisticated, computer controlled, turbocharged Honda.
Cons: picky about spark plugs
Vehicle:
Honda
Autolite are garbage plugs. Get denso or ngk plugs and gap them accordingly before installation. You can see signs of blow-by at the porcelain.
Cons: garbage plugs, signs of blow-by
I dug factory installed spark plugs out of my recently departed E90... they looked like something from the stone age. 19 year old car, and from what I could tell, never had the plugs changes.
Cons: old spark plugs
Vehicle:
BMW
I agree with everyone saying NGK but I would also like to recommend you do not buy an autolite if you need a substitute, they have horrible quality control.
Cons: horrible quality control
