use BMW OEM plugs from the dealer. Yes the are expensive but I have never had a problem with misfires and I've put over 100,000 miles on my current E36 and over 150,000 on my first. While they are suppose to work and be interchangeable according to the manufacturer the NKG you buy aftermarket are supposedly different than what you get from BMW
Owner reviews for spark plug
I got a 49cc Bintelli Sprint brand new for about 2K. The only problem I have with it is it needs a kick start on cold nights. The only maintenance I've done is change the oil, spark plugs (unnecessary) and lube the Kickstarter.
The ER12S look better than the OEM units that came out on the first change, these have been in for a year.
I'd use the original equipment AC Delco plug. Rockauto has them for $6.31 each, with a $3 per plug rebate offered.
Ran Autolite Iridum XP XP3922 plugs in it and had zero issues at about half the price of the NGK plugs, and I had a mild tune.
Get the hks plugs, they work fantastic for the stinger.
I bought NGK-94833 spark plugs from FCPEuro for my 2015 Jetta with the 1.8T.
I do need to change the spark plugs. I haven't done that in 10+ years and 100,000+ miles. It just started misfiring slightly I believe (haven't checked the code yet), but it runs and drives well still.
it was the Autolite spark plugs. Had car towed to my mechanic. They replaced with spec NGK and the car is running fine.
Ngk are trash. Go with oem Bosch
