Yep, what Joe said. I went to Walmart(yeah, well it wasn't for the truck) to get just TWO sparkplugs for my lawnmower and it called for Champion plugs. Well, I get to Walmart, and every single last one of the plugs hadn't been assembled, or had cracked ceramic, or the list goes on and on. I don't really have anything against the company or their product, it's just that I wouldn't use them in a truck unless I knew the ones I bought were okay.
