To make power and get good gas mileage, You need to completely burn the fuel that is in your cylinder!! You can get a high voltage aftermarket
coil and open up your gap a tad over the high range spec just try like .55 to start with say if it is .50 max stock gap. You want to expose as much
of the spark to the fuel as possible, Sure you could try those bosch and other plugs that open up the electrode, But with a widen gap on a stock
plug with a coil that can jump the gap will do the same thing for a $4.00 a plug savings$$ After a couple of plug changes the coil will have bought itself!!
Compared to buying those special plugs. Getting high performance plug wires and ensuring that you are not getting crossfire or sparks to ground so
there is no waste of spark energy will help. Spray the plug wires at night with a mister of water, turn off all lights, start truck and look for sparks jumping
you need to minimize the errant sparks by rerouting wires adding isloaters or covering the wires in splitloom which looks pretty cool BTW!!
