I was just curious on how a throttle body spacer actually worked and how it creates more hp? Thanks

 

it has been discussed on here before, try a search. but i think they add more plenum volume than anything, they might help swirl air intot the intake, but on a honda your money is better spent somewhere else.

 

It swirls the air from the throttle body. But in order for it to really work well, you have to have the airaid one like I have. It comes with a little whistle that acts as another intake, so the air from the intake and the air from the spacer hit each other and brings it into a swirling pattern. Unfortunetly, I keep the whistle out of mine as it makes the car idle very weird. The Hp gains are pretty minimal, I'm getting rid of mine when I get a bored out tb and port matched intake manifold. Save your money and spend it on something better. It probably works better on bigger engines.
