I wouldn't order the plugs just yet. The factory plugs are good for 110,000 miles, without a time limit.

However, I would remove the plugs to check for oil on them. (leaking valve cover gasket) Also, have a look at the tips/gap/colour and inspect the ignition coil rubber boots for cracks/rips or white arcing powder/dots.
