My Brother-in-Law swears by
K&N Air Filters. He buys them for every truck he ownes and tries to convice me to purchase them. I may be buying a Dodge soon, does anyone know if these actually help gas mileage like he tells me they do?
Also, does a true duel exhaust help MPG?
Finally, would just dropping the tailgate and/or purchasing an
alternative tailgate which allows wind to pass through help as much as a canaopy? (It may be cheaper).
