I can't decide which sparks plug to choose between these two.
NGK OE equivalent spark plug is the Laser Platinum PLKR7A stock no. 4288
Or
Bosch Double Platinum Spark Plug
On mbworld.org forum people are getting better gas mileage with NGK Laser platinum and a lot of people switching over to ngk over Bosch oem. I think Bosch plug was a colder plug and people switching to ngk which is hotter plug and no wonder they're getting better gas mileage.
On Bosch plug no anti-sieze is required and I don't know about ngk.
I want to know if mecredes put in colder sparks plug then I want to use colder plug and not change them to hotter plug.
Please correct me if I'm wrong and my information about.
