Id like to pick every ones brain for a quick moment if that would be okay. The mods i am almost sure work that i plan on doing are the electric fans on my 2001 F150 4.6, the bed cover, 50 psi tires and new oxygen sensors but there are a few i want to ask about.
1. I read all the time about how air intakes are suppose to raise your gas mileage, is this true or not.
2. I'm not a huge believer in fuel additives, but is there something out their i have been missing that really does work?
3. Would lowering the truck 4 inches really yield a noticeable increase? Enough of one to justify spending 400 on getting it done.
4. Would a 5-10 degree hotter thermostat help lean the mixtures out some.
5. Does lowering the tailgate really work?
Sorry for all the questions, i have never had access to a community such as this one before and i think you all would be the best to ask.
