Correct Spark Plugs

BIG_KID · 06-23-2023, 08:07 PM

I’m changing the spark plugs on my “new to me” 2014 X3 35i
The plugs I pulled out are NGK SILZKBR8DES (one step colder than stock)
The stock plugs are Bosch ZR5TPP33. The car is bone stock. What plugs would you guys go with on this. Thanks.

Go with the stock Bosch plugs. I’ve got 167k miles on our X3 35i with Eldor coils and haven’t had any issues.

Agreed. Go with stock bosch plugs. I think they part number you listed has been discontinued and they've replaced it with that same part number +"S"
