Go with the best grade delco plugs you can get for your engine. In my opinion, at least.

I agree, AC Delco only in the 4.3L engines.

I have a 1998 S10 Blazer, there are 2 plugs I can not seem to get to. Is there a trick to this?

All plugs except #3 can be accessed by raising the front wheels off the ground and working through the wheel wells. To access #3, disconnect the steering shaft from the steering gear and move the shaft aside. Don't allow the steering shaft to turn while disconnected from the steering gear or damage to the clock-spring will occur.

At the very least make sure to use platinum plugs. I put a set of NGK's in and they are working great!

I bought a spark plug socket that has the swivel built into it and I use that with no problems. Might be a thought instead of removing steering stuff.
