What are good MPG upgrades for Expedition?
What are some good, affordable upgrades(besides K&N) that will give our 99 Expy w/5.4 and 3.73axle better MPG. Also, will some upgrades hurt towing power? what upgrades will help towing power? The reason I ask if any upgrades will hurt power is because my uncle had put headers on his truck and they killed his low-end torque.
thanks
