Spark Plugs

[cao88c]

Hey guys, I need to do a tune-up to my 1999 Suburban (4x2; 5.7). Which sparkplugs do you guys usually go with?

 

Please don't tell me Split-Fire, or E3, or any of those "gimmick" spark plugs, just something you can get at autozone.

 

Thanks

Go w/ some NGK TR55's. If you prefer platinum step up to the TR55GP's.

AC Delco work fine for me. ALSO.. put some Anti seize compound on the plug threads before installing them, and some Dielectric grease in the plug boots.. you will thank me the next time you replace them..
