I've see these new spark plugs done by lamborgini look the business what the vid. Reviews from states say guy got extra 20 miles on a tank as pulled cleaner through revs and didn't need to plant it as hard.
Here's plugs out of chamber firing
Just search for DOR17LGS the green spark plug company do them for about 45 for a set of 6 so ordering some tomorrow I'll let you know how they get on in the truck when they arrive. Ideal for lpg trucks as well.
