i am about to replace the spark plugs in my truck and im not sure if I should use ac delco plugs, i have never replaced them and the other owner had them done at the dealer so i know they are ac delco. i guess what i am wondering is if other brands of spark plugs cause any sort of driveability concerns? if you read this and dont have any driveability concerns after spark plug replacement please post what spark plugs you used! THANKS!!

 

AC Delco Double Platinum, NGK Double Platinum, or the premium Iridium plug (iridium center electrode with platinum ground electrode) from either of those two manufacturers and you'll be set for a good long while.

How many miles do you have on your truck. The original plugs can last up to 70k without breaking a sweat.

 

i have 107,xxx and i am not sure when they were replaced last, i have big road trip coming up and figured it couldnt hurt it to put some fresh spark in the block!
