    I was just wondering if anyone uses a throttle body spacer and if they really help with throttle response torque and horsepower or if it would be a waste of my money. I appreciate any help thanks.

    I had one for awhile.... It caused conflicts with my TV cable adjustment, which in time led to the dimise of my tranny. (thats another story in itself....)
    It seemed to help on upper end performance, but nothing terribly noticeable. My truck hardly ever sees anything above 2800 RPM so i dont believe it did me much good. If you buy one,..... make sure it comes with spacers to raise your Throttle bracket. I can tell you from experience that the POWERAIDE brand does not !!!! Thats all i will say about that.

    IMO save your 75 or 80 bucks and get some stuff that will really help performance. Look at a dual snorkle intake with tubes flowing cool air in or/and get the INJECTOR spacer from Turbo City... it runs about 20 bucks.It raises the injector up a tad to help allow a bit more air in.

    You should save your money for a new Holley TBI and not fool with the spacer if you can't get both. I'm getting ready to put both on my 2.8L soon.

    Thunder... How does that air flow inhacer install? Did you weld or rivet it onto your stock assembly? I know when we were experimenting on the dyno that carb stack type elements actually got the best all around hp so I think that would be a bretty decent mod.

    The install was a piece of cake
    I cut out the hole bigger on the stock air cleaner housing with a jig saw. then riveted The air flow enhancer on on and sealed it with silicone. It was a easy job. took about 1/2 hour It comes good instructions, rivits, and the fitting that the breather hooks up to.
    Nice performance boost for $40.00. It works best with headers and good exahust.
    The injector spacers were also a pretty easy install.
