Is this a good product? Just looking to get better gas mileage and the extra horses. mainly because everytime i get on it, the engine bogs down. any help would be good. thanks

 

I know the spacers sell really well, at least there is a market for them. They were originaly created to space carbs away from intake manifolds on older engines. When I used to have an LT1 Trans am, all the reading up i did said that the spacers effectively did nothing but look pretty and gave no performance gain to a fuel injected engine.

 

I have a 98 4x4 2 door and i have a e-bay intake, helix power tower spacer and a cfm-tech throttle plate and on a 3 hour drive i got 25 mpg so i dont know what worked but it did.
