    Throttle body spacers (TBS) came about back in the time when TBI engines were the craze. The TBS did indeed help the TBIs as they helped to improve atomization of the fuel by changing the flow of air as the fuel was sprayed before the throttle body. The gains are minimal but are still there.

    The TBS are a waste on the newer engines as the fuel is sprayed after the throttle body. The air is already "spun up" as it goes through the throttle body, so the TBS basically duplicates the effort. The TBS won't hurt your engine however, that being said, some folks wind up having problems with the spacer as it is one more thing to wiggle lose and cause leaks.

    I put an AirAide throttle body spacer on my silverado and it did make a noticeable diiference. It revved a little faster and made a cool wistle sound. That tbs combined with my intake makes a lot of noise but its cool sounding. Anyway, i wouldnt get any other spacer than AirAids.

    For the money, it's better put towards and air intake or even a muffler.

    If you can get one for under $50 go for it, but I wouldn't spend anymore than that on one. I was able to buy one for $42 or so on eBay, where as other sites wanted upwards of $150. It's hard to tell if they really do "work" or if the placebo effect is kicking in. Only real way to tell is to have your truck dynoed before and after the installation.
