I used to think all spark plugs were the same until my truck started misfiring on I-35

Yeah, cheap plugs are hit or miss with most modern engines.

Bet on cheap plugs and you're basically playing roulette with your check engine light.

idk man, I kinda disagree with @charlesowens on this one. I've run cheap autolite plugs in my old F150 for years and it purrs like a kitten. Most misfire issues come from bad coils or worn wires way before the plug itself is the problem.
