But yea, it sure is nice having an inline 4. Plugs can be changed in minutes instead of hours.
I don't think DOHC is automatically easier to change plugs on. Look at Ford Taurus 3G and 4G, their Vulcan (pushrod) is easier to change rear plugs (with hands in the rear bank) than the Duratec (need to remove manifold).
Fair enough, but then you can say 4 bangers aren't automatically easier to change because some of them (Nissans), you have to remove the intake manifold as well to get at the plugs.
