New Plugs on 2012 Eco = 2.5 MPG Gain (City)
#101
Should I gap at the same (.030) with a stock truck besides exhaust? Not sure if you all have tuned rides or just stock..also, I'll be adding a CAI soon which I've heard will cause the truck to run lean. Would adjusting the gap up or down help to eliminate it running so lean? Auto rookie here, lol.
