it seems as the engine bays become more packed full of goodies, the notion of maintenance ease for serviceable parts deteriorates!
regarding how the car performs after the plugs... I went stage 3 a week later, so i didnt have too much to compare. However, i did seem to think that the car ran a bit better and smoother. Cant comment on the mileage, as most of my driving was highway after the plug job.
