For me went I was ready for new plugs,I stay with A/C Delco. Iridium Plug's.But it depends on what you are looking for in a plug,and what Performance Mods you have put on your Ride.I've been pleased with the A/C Delco Plugs.I have not really looked into some of the aftermarket plugs,maybe someone else can give you some input on them

I just got Bosch +4 plugs in my truck last week. I can really tell a difference in throttle response and the ease in starting my truck. I seem to get more acceleration with them too, i also got new spark wires the day after, and i noticed another increase in the same areas with new wires. I recommend them, i like mine a lot.
