Plug Gap = MPG
My L-92 test.
I am about to fit my IGN-1A coil kit to my 2007 Escalade.
The baseline is a 50K driven millage @ 22 MPG "best" freeway, even grade, both ways at 38 mikes each way, tested over 50 times.
The sparkplugs have never been changed.
New plugs gaped at .040" for the first part of the test resulted in a 1.6 MPG LOSS tested 12 times.
The next phase will be to ONLY OPEN the GAP to the OEM GM .060"
My guess is that the mileage will return to normal ?
