I have read the above sticky about the Spark plugs, but I was more curious about what kind of Spark plugs is everyone using. Are AC Delco's the top choice or is there something better, ie, NGK's, Champions, Autolites. Thanks

 

I think its a matter of personal prefrence like oil - some companies make it purple, some have clear bottles - at the end of the day they all work well. I have NGK plugs in mine. I use NGK plugs in all my vehicles. AC Delco is the factory stuff, so if you want to keep it as it was, then use what they came with I guess...

 

Ok thanks. Do you know what the part number is for the NGK's that you use.

 

AC delco would be my first choice than autolite. Avoid bosch by all means. Haven't heard great things about champion and I'm not sure about ngk except when it comes to snowmobiles.

 

use AC Delco's only to avoid misfires! and second choice Autolites only because they are made by the same company that makes AC Delco's.....any other plugs will cause misfires, especailly Bosch!

 

Yeah, Ac Delco would be my top choice.

 

AC Delco

 

wow thanks for the recommendations everyone. Very helpful to me and hopefully others.
