Re: Throttle body spacer

You may want to try using the search feature. Quite a few folks have installed them and you will get the full array of opinions on them.

Re: Throttle body spacer

I had one and had it dyno tested when I had my Unichip tuned. We got inconsistent results, and no improvements that you would ever notice. Here is a link to the dyno charts.
Unichip Computer module

It seemed to help a tad down low, but did screwy stuff up at the top end. I gave mine away.

Re: Throttle body spacer

I put mine on about 2 months after I put the CAI on. there has been no power increase, the gas mileage is the same. The only thing is you can hear a whistle...

Re: Throttle body spacer

Something just occured to me...
A throttle body spacer would hurt performance by by giving the air more time to warm up before it enters the combustion chamber. We already know that there aren't any gains, but my thought was that the performance stayed the same. Now I dont think so...

Re: Throttle body spacer

I think its no big deal either way. It won't hurt much and it won't help much.
