May have to remove intake manifold to access rear three spark plugs.

There is no "rear 3"  it's a four cylinder.  Remove the plastic engine cover.  I believe you will have to remove the coils, but the whole job is pretty easy.  You need a spark plug socket, 12" extension, ratchet, and some thread anti-seize.  DON'T GAP THE PLATINUM PLUGS.  Put anti-seize on the threads, and tighten until you feel the crush rings give and the plug tightens.

Yep go with the second guy.  It's a 4 banger.
