I cannot see how that could be any help to your car. Even the best throttle body spacers do very, very minimal help performance wise to your car. HP increase is basically none, but I hear you can go up 2 MPG with a good spacer like Stack, Steeda, or AFE.
Overall, I would say its just like anything dealing with cars. Generally, the more you spend on an item, the more performance you will get out of it. You aren't going to get much at all, but you might see a difference in the MPG, and MAYBE some HP increase or acceleration.
this...like maybe a fine whore. it'd do more for your car then a spacer would...hell even an intake spacer won't do ****.
@op...gotta pay to play if you want to make a v6 quick (notice i don't say fast lol)
