well it is pretty straight forward if you get a set of wires that are pre cut for the car then just have a deep sparkplug socket and take them out then I lube the tips with dielectric grease and then put them back in and do the wires one at a time much easier to not forget one other then that nothing to it
it is easier on a cooler engine
get a few inches of vacumn hose too. stab the new plug, (not the threaded end) into the hose and use the hose to start the thread. Hose should grip tightly enough to start but if it cross threads into the head, the hose will slip on the plug and not damage the threads in the cylinder head.
