Throttle body spacers....

[JonBishop]

Was looking at the poweraid throttle body spacer..... What's the pros and cons to throttle body spacers? Seems like its jus there to make a little hissing sound haha

Don't get the throttle body spacer, everybody says that is not worth it and it is useless, and everybody who has one takes them off. If anything, get a ported throttle body from supermod

Throttle body spacers are hold overs from the old carburetor days. Spacers would increase the velocity of intake air and improve fuel atomization and fuel/air mixing before it all got into the cylinders. Modern engines use fuel injection, and the fuel and air don't contact until right at the cylinder. So spacers really do nothing at all on modern engines.

"Everybody says" is not too scientific. I think the misconception is that it will make a great deal of difference without any other mods like adding a 4 barrel used to. It really sort of sounds like snake oil and the good ones will not make that whistling noise if built right. It sort of completes additional mods. It does come up that why would the manufacturer of the vehicle not want to use them if they really worked. Lots of speculation on that.
Dyno runs do show improvements.
I was offered one to try if I brought in my 06 I-5 as they had not tried it on one. However being all wheel drive they could not run the H3 on their dyno. They did run a Colorado and had some improved results.
I think the reason people remove them is they did not jump in and fire it up and be blown away by their seatopants dyno. Like I mentioned from what I learned was it is subtle but adds to an overall package.
I guess if you don't want to spend the money, going with the crowd that did not evaluate it properly would be a good excuse not to have one.
The never ending story................
It's too late tonight but I will add some pictures.

The only change you could guarantee is that they do make your wallet a bit lighter :wink:

Ha ha maybe it's more of a "feelgood" cure. Like fish oil? I certainly at least tried it but sort of decided, well, I don't know for sure. I would think the engine controls would just compensate for any change. They sure sell the heck out of them though.
This was also the place back in 9/26/06 that I started experimenting with the intake tube at the same time. They wanted to leave in that OEM accordion tube and I did not. They claimed it would prevent breaking motor mounts. I knew right then we would part ways. I mean come on, I use hump boots and made my own. I did not like the open design either. "cold air" yea right. OEM was has a cooler source. I felt at the time that the liability of selling these not knowing how they would affect warranties, I held off. Then GM finally got in gear and made a $$$$ intake and all of a sudden, not sure when that came out, it was ok with the dealer then? So I had one on the I-5 of my design and now on the Alpha of my design. They never made any at that place.
I did have a great tour of how things were done.

so now you know "the rest of the story" I miss ole Paul...............
now about those magnets??????
