Re: NGK plug #, 2000 5.3 ?
Stock is like .060 or something huge. They work like that, we gapped down just a bit.
.050 to .060 is normal on those plugs, you can go further, but if thats needed then there is probably something elsewhere that should be changed instead.

Re: NGK plug #, 2000 5.3 ?
Thanks again
 My bet is that the MSD box should fire the plugs with a .045-.050 gap  Longhorn
