I just bought some Champion Copper Plus spark plugs. I know I should be using Motorcraft ones but these ones were so so so so so cheap and I heard they work good.....if they don't I'll go get Motorcraft ones and call it a lesson learned. Anyways, it says that they are gapped to .044, and I have no clue what they SHOULD be gapped to. They are going into a naturally aspirated 2.3 if that makes any difference.
Anyone?
Anyone?
