I usually get the front 4 through the wheel well with a long extension, and the back 2 from underneath "by feel" since you can't see them. Astro's don't eat spark plugs. They eat ignition wires and distributor cap and rotors. I would use only Autolite Double Platinum plugs. I have had 4 Astro's and I have had the best results with this plug.
