What kind of Spark Plus do i need
 

I have a 87 300E. I want to change the spark plugs
Can someone tell me what kind I need, and how to change them


thanks,

I don't own a gasoline Benz, but my money is on Bosch being the OEM plug for any gasoline Benz.
OK, I just looked up your car in the Fastlane catalog and the plugs are Bosch, however which Bosch plug depends on what month your car was made. One plug is for cars built BEFORE April '88 and then another is for cars built from May onward.

I have a '86 300E...........Use the recommended plugs, or cross reference them to Autolites or AC, and save yourself some money!! Don't even think about "platinum bull****" plugs! Only copper core for our cars! I just did my own test.....I purchased the Bosch Platinum core plugs and my car idled worse. Went back to the copper cores and.........:D ,smooth as silk! The best part of my own test is I brought the plugs back and got my money! I'll get you the Autolite p/n if you need it, that is what I use. Why pay more?

6 cyl. motor -> Bosch H9DC0. Std. gap is .032. Some say a wider gap yields smoother idle.

Go with the Bosch and stay away from the auto-zone cross referance plugs, they last longer and are the factory equipment.:D
