I could change out the plugs on my old 93 Z28 Indy 500 Pace Car in under 3 hours easily. Changing the wires was a different story, especially with the supercharger getting in the way on the driver's side. No special tools needed either. Don't let a shop rape you, plus they could screw something up and say it wasn't their fault.
