Spark plug gap issue
Was getting ready to change the plugs(AC 41-993) in my '04 s10 blazer and found they are all gapped at .065, not .060 like vehicle requires. I've read mixed reviews on gapping these plugs and wonder if anyone else has had a problem with gapping 'em?

I would gap the plugs to what the book says, how old are the plugs? (mileage)
#3
I have around 50k on the old ones, I think I used autolite last time. Just found it odd that OE plugs are not gapped to spec.

YOU should gap the plugs. Don't ever expect the manufacturer to gap plugs.
#5
Stick with the AC/ Delco platinum plugs they work the BEST for these trucks. And always double check the gap settings on your plugs.

3 is easy
go through the wheel well... deep well socket, swivel adapter, 6 or 8 in extension
