Spark plug gap

[FastazzL]

I did a search of the forum and found lots of answers on what the gap should be if you have certain mods, but my truck is still stock. I'm not sure what the gap should be with my stock engine so if somebody could chime in and let me know, that would be great. I just want to get the truck ready for the drive down to the GTG on the 28th.

I ran into a similar problem a couple of weeks ago. Here's the only help I can give you:

I went with .036, but I'm modded. Just search the threads or wait for an answer. I think my stockers were gapped @ .043 when I got them out.

I agree i set mine (Tr6's) between .036-.038. My stockers were anywere from .043-.046.....Ooppps didnt see you were stock....What Slider said. :beer:

If you are not modded, then stick with the stock gap.

FastazzL, on a stock Lightning, I would gap them at a tight .040 for overall driving, without any pulley modifications performed on your vehicle. Also, if you do decide to install a 4 lb. or 6 lb. Lower Crank Pulley later on, then I would strongly suggest you gap them at .035 .037 , to help lower the cylinder temperatures and optimize performance , under wide open throttle.

Hope this helps, as I am a firm believer in NGK TR6's , even gapped at .040 on a Bone Stock Lightning, verses the Iridium or Platinum plugs.
