Spark Plugs What Do You Prefer & Why?
I''m getting a misfire every so often on plugs 1,3 & 4
its been long overdue for me to replace these
is there any brand that is better than another
or works better in our rigs
I was thinking Bosch, but somewhere I once read ACdelco work better
any help is greatly appreciated
