Throttle Body Spacers

I was wondering how many of you have tried out throttle body spacers on your trailblazers. I have an Ext with the 5.3 and would like to put one on it. Do they make much of a difference? Poweraid makes one that is about $100 for mine, so it isn't that expensive to experiment with. Just thought I would ask for some imput. Thanks. :lol2:

Sure....now you got me thinking about that now :biggrin:


Must have MORE POWER!

So....did you get one or not yet?


If you did, how did you like it & what did it do for you?

No - I am still feeling people out on their experiences with them. Plus, I have read that they are pointless to use with Vortec engines since these engines are designed to do the same thing by default. I will let you know if I do it though.

I put a Poweraid spacer on my 02 TB about a year ago and have noticed a slight increase in power, but mostly in fuel efficiency. BOth have increased slightly. I think it is a pretty good deal.
