do they work? and what do they really do. i heurd so many diffrent things

 

I suppose it depends on what engine your truck has (4.7 ? 5.7 ? 5.9? CTD ?)....I've not tried one, but all I hear from the good folk on this forum is that they are junk...paperweights, a waste of money (thus, I've not even bothered to try one)....

 

Really depends on the engine, or I guess the design of the throttle body itself. I've seen the dyno's on a '98 Chevy a few years back show almost as much gains as a CAI, but nobody reports any gains on a Hemi and it supposedly makes a god awful whistling noise on the Hemi as well.
I read a post on another Dodge forum about a year or so ago where the guy supposedly dyno'd his '05 before and after where it actually showed a slight LOSS of performance...

 

I took mine off and throttle response actually felt better.

 

Expensive paper weight

 

I think I read a post or two up, that gains from a throttle body spacer can basically only be achieved by a certain type of throttle body. So my question is, what is it about our throttle bodies (maybe intake manifold design?) that makes it moot to install a spacer?

 

ok. sounds good. wont wast my money on that then. lol. thanks alot guys and how do you get the stars up next to your name?

 

It's not so much the type of throttle body as it is the way the fuel/air is delivered. On a wet manifold setup (carb, TBI, etc) the spacers get decent gains because the fuel/air mix before it gets into the intake manifold. On a dry setup (Hemi, LSx's, most modern engines) the fuel is injected directly into the head so the spacer doesn't do anything.

 

you gotta keep posting to get the stars. the more posts, more stars.

 

I've got an AirRaid.

The whistle is very light. Sounds like a turbo.

Speed Safely,
