Answer 1
Labor guide says over 2.5 hours The front plugs take .5 hours the rear plugs should take between 1 to 1.5 hours. -
Answer 2
You have to remove the manifold. I'm getting the transmission rebuilt so I had them swap out the plugs while everythings out, go with iridium so you don't have to worry about them for another 100K. -
