a lot of work and time is involved replacing just spark plugs cuz of having the intake runners on top of engine cylinder head.
the intake runners running on top blocks the nbr 4 and 5 cylinder so you can take out spark plugs from them.
you need to take out trottle body assebly, slide it out.
unplug all hoses, including bypass hoses that's attached to throttle body, unplug throttle position sensor, disconnect accelerator cable.......lot's of work man......but it will save you 100 fr labor........good luck
