OK SO, Have you seen any increase in performance? If so, I'm going to order one. I'm actually waiting to hear from your experience if you notice a difference or not after installing it. I think we ALL want to know ;-)

My thoughts on the SPACER..I think it's snake oil..I've mention this before..

The turbulance it is suppose to do to the intake air is before the intake manifold chambers and throttle body, which they themselves do that job of swirling the air..So IMHO, it is redundant to pre-swirl the air before the Throttle body with this Spacer..

And since this engine is multiported with 5 individual injectors, the intake chamber after the throttle body stirs up the air by design...

So this concept of swirling the intake air would have some merit with these TB spacers on Carburated or Throttle body injection systems.

But it's worthless on these type of injected engines.

So, what you are truely saying is topcarbon should have just sent his money to me because it would have had the same affect on his H3 that it does now invested into that part ;-)

Exactly...But I was thinking more along the lines of sending ME the money..you got enough!

That's right buddy. Remember, I'm rich because I drive a $65,000 H3 and get 4 mpg!

I talked to a president of a company that designs the TB spacers. He basically said that if you have a restrictive air box then the TB spacer will help by increasing the available manifold plenum volume. If you have a low restriction air box, the benefits of the increased plenum volume decreases and the TB spacer isn't worth the lower gain.

Thanks for the info. We appreciate it. I have a K&N filter but the factory air box. Would that still be considered restrictive, or less restrictive? I was actually thinking about cutting a few air vents in the bottom of the box near the side where some air comes in through the gaps in the headlight housing to suck up extra air if needed.

When I had my camaro, I actually made a custom housing using that thermal engine compartment insulation and wrapped my entire air intake system with it to keep it cool. It seemed to make a difference.

You seem to know alot of detailed technical information about GM products. Thanks for helping us out. We all seem like novices compared to you :)

Okay, so here are some early results of the new stuff. On exclusive highway driving, speed of 65-75, there was a marginal increase in fuel economy. Maybe .5 miles per gallon. As far as pickup goes, there was a smoother power down low and for passing. I was able to smoothly go from 65 to 80 with little effort(less effort than before). I think the real difference will come when I put the Magnaflow Cat Back on next week. Although I am not overly impressed, I am not disappointed either. Hope this helps. Any improvement with little money out is always a good thing.

Cool. I honestly just want to avoid going to the gas station as much as possible. I was going to start taking the train to work every day, but now that all this terrorist stuff is acting up again, I think I'll just suck it up and keep driving. With as many people that take the train into the city everyday, I don't want to be one of those people that thinks "Oh that won't happen to me" and then be on the news saying "I didn't think it would happen to me" :)

(don't tell my wife, but it's just a really pathetic excuse to drive to work every day.....) OK well, there IS some justification in it.

Mike please take the train. If you drive to avoid terrorism you are letting them win. I work in the tallest building in Century City CA and it is considered a prime target. Do not believe everything you see on TV.

Get the K&n full kit nad you will be happy. Just ask the smart guys here Dennis, Dilo and Mr. Invisible.

Oh I know. Like I said, I'm just using it as an excuse to drive :).

Our lawfirm has an office in your building. You dont work for a lawfirm by any chance do you ;-)

Here in Chicago I work within walking distance of the Sears Tower. If I was afraid in that respect, I wouldn't be working in the city.

Does anyone have a link or suggestion for a larger throttle body? Has anyone done this and what were the results?

What Fireman was saying was that he put on a larger throttle body which obviously had a larger Injector in it..hence the more fuel..I think then you are right about the I5, whereas it is a multiport fuel injected and has 5 individual injecters (one for each cylinder)..Whereas, a throttle body injection system, has one big a$$ injector in the throttle body for the whole engine (GM did this a lot on their first injected engines back in the 80's)...All we have on these I5 engines, is a butterfly valve in the throttle body to regulate air flow.

Correct. All the throttle body does it open and close the butterfly valve (regulating the amount of air going into the engine), and send a signal back to the computer for the Throttle Position Sensor. It has nothing to do with fuel delivery, other than if a larger diameter one is installed you might theoretically get more air in, which would result in more fuel from the 5 individual injectors in the intake manifold.

In a TBI vehicle (throttle body injection), a spacer might end up increasing engine torque a little bit because of the increased runner length, but I'm not positive about that. That might only apply to vehicles with a carb.
