Answer 5

a simlpe rull of thumb to remember is that as long as it isn't any kind of pro... series part from pepboy's, or trak auto your ok. as to boush, i run them in my 29' ford & love em. as w/ anything automotive you need to follow specs. folow gap requirements, but a better product won't make your car fall on it's face. all spark plugs are not created equal. there are different medals and better plugs, but for a daily driver your good. happy throttel'n

Answer 6

AC Delco.
