06' Titan, just rolled 80k miles on the odometer. Would love to upgrade to hotter spark plug perhaps performance wires, if it would make a difference. installed 24 inch alloy wheels has hurt mileage a little, getting right at 400 miles on a topped off tank, is this normal? a few other little issues that could use maintenance.. any suggestions or tips, what to look for and avoid? also send details on installs or howtos, as well as pics
