well it won't give you more power, but it will give you almost instant throttle response. I had one on my prelude and I really liked it. It took a while to get used to the pedal feel after I installed it, but for the price it's a pretty useful mod. As far as getting a bigger throttle body, i suppose you could get one and pick up 5 hp for a mere 2 or 300 dollars, but larger throttle bodies aren't very beneficial unless you port match the hole on the intake to the throttle body. that's when you start to see nice gains from a TB
