There's a piece of black plastic running down the center of the valve
cover...remove this and the spark plugs are in wells below. These are
embedded deep in the head and the spark plug boots can be a pain to remove /
replace. After gapping, use a piece of 1/4 vacuum hose on the end of the new
spark plugs to hand start them to avoid crossthreading, use some dielectric
grease on the boots, and use some anti-seize to keep the threads from
galling. Hope this info helps....some of it was learned the hard way.
