I have a 2000 Durango with the 4.7 looking for a little mpg increase. Was told a throttle body spacer from air raid would help me out. Was wondering if anyone out there has tried it or has a brand that does work. Thanks.

 

Throttle body spacers won't do anything, they're just paper weights.

 

Throttle body spacers work by giving the fuel and air a bit more room to mix before entering the intake. Since a fuel injected vehicle has no fuel in the throttle body, they do nothing.

 

Their only purpose is to differentiate thinking people from lemmings.

 

Thanks guys. Probably just try an intake then.
