Thanks for the information everyone. Looks like the plugs were changed by the dealer.
but the wires are the originals
. Is it difficult to change the plugs yourself? If I do the wires then I might as well upgrade the plugs while I'm in there. I looked through the walkthrough on the sticky and it just seems to be too simple
Is it really that easy? Any idea on better plugs for southern climates vs northern. Seems everyone goes with a good platinum plug.
