I replaced the plugs and wires in my 2000 Tahoe this morning (5.3 motor). The best tip I picked up was the importance of using some channel lock pliers to remove the old wires - they are VERY HARD to remove (I was at 130K miles on the original plugs/wires). Don't be timid, grab those suckers on the rubber boot with the pliers and then find a leverage point to pry them off. You will be reusing the metal sleeves that cover the rubber boot, so dont' manlgle them too much.

The rear plug on the passenger side is the hardest to remove. I suggest you start with one of the easier ones to get your confidence up, then tackle that little sucker with both hands.

Oh yeah, I wish I was about 6 inches taller, as it was a bear to get over the fenders (I'm 5'9" with a 32" inseam).

The AC Delco Iridium plugs plus the "lifetime warranty" Duralast wires cost about $117 from AutoZone.
