TBI spacers

[94chevy4x4]

I have been looking at buying one and i have hear that they help your gas mileage. Has anyone used these or know anything about it?

Supposedly it helps on a TBI engine. I don't have one though.

 

[94chevy4x4]

yeah im looking to get better gas mileage .. my next step is putting an electric fan instead of the clutch fan

Fan ??????

Come again over !!!!!

yeah the clutch fan that cools your radiator .. take it off and replace it with an electric fan .. it cuts down the load on the motor and free's up horse power and mpg

TBI Spacer and a e-fan are great upgrades for a TBI Motor!

dont use a spacer on a vortec though, it does nothing.

Mixed reviews or not, it does absolutely nothing to the Vortec motors since the poppets are right behind the intake valve so there is no increase in atomization but it does make a cool sound

yeah im not looking for the sound im looking for the mpg
