Will this fit?

I have a 1999 Honda Prelude and I am assuming its the base model. I have the sh wheels and sh rear spoiler but I have no idea if those were added by the previous owner. Anyways I found a throttle body spacer but the application guide says for a 97-01 sh is there any different in the throttle bodys on these two applications....from what I can see there is no difference.

throttle body spacer = waste of money

This was taken from truckblog.com

The Theory
The throttle body spacer is based on the theory that air entering a chamber will have a greater velocity and more mass if it spun. The helical groves on the throttle body spacer are designed to make the air start spinning as it passes through the grooves, thus delivering a greater volume of air to the ic engines cylinder and in turn, increasing the power of the detonation by adding more air to the fuel/air mixture. Additionally on older model vehicle with throttle body injection, the swirling air mixes the air and fuel much better, providing a more consistent spark and hotter detonation. More Air & stronger detonation = more Power. In addition to the increased power claims there is the claim that you will also experiance gains in fuel ecconomy as less fuel is required to make more power, meaning you will be able to save gas (up to 10% if you believe some of the manufacturers) if you don't alter your driving habits.

The Reality
Late model fuel injected cars and trucks have their fuel and air mixed just prior to being injected into the combustion chamber, meaning all the swirling going on in the intake manifold isn't happening with the fuel, so the "mixing" of the air and fuel doesn't happen. Older, carburated vehicles and ones with throttle body injection (older than a '95) can benefit from this swirling motion, however your brand new port injected Chevy Siverado isn't going to benefit at all from this action other than making a weird high pitch noise from under the hood that some kid might mistake for a turbo.

The Facts
We equipped a 2001 Ford Super Duty V-10 with an aftermarket throttle body spacer made by one of the name brand manufacturers out there. Prior to this test the truck had been modified with a cold air intake system and full 3.5" exhaust system from the headers back. When getting a baseline dyno, the best pull rendered 283.4 hp and 361.4 lb-ft torque (corrected for 93°F) at the rear wheels. After the addition of the throttle body spacer, the best we could pull 281.1 hp and 354.7 lb-ft torque. Now, we will concede that the engine was getting hotter and so was the day by the time we had the throttle body spacer installed (approx. 20 mins later) but according to the manufacturer we should have had an "noticeable increase in power" which is contrary to the reports generated by the Dynojet.

I have read in magazines and seen on power block tv that throttle body spacers DO make a difference. But I guess you're right, it doesn't work on all engines.

older engines yes, it might even help on a newer engine with nitrous or methanol injection (depending on the injection point)

thanks for the input. Makes a huge difference not gonna waste the 120 bucks if its not gonna make a difference....how about this what about those weapon r billet throttle discs? Do they make acceleration any faster...they claim its 50% of the stock rotation which makes you get to full throttle faster over stock. All im looking for is some more power and better fuel economy. I will never be taking this car to the track in any circumstances (1/4 or circle track)

ever nees the tornado thing u put in the intake tube. They don't work b/c of what apt_lude posted. If it was N02 it might if it was mixed b/4 the TB.

I don't see why it wouldn't do what it says and open your throttle faster...but I also don't see how that would really help, unless you were drag racing and fractions of seconds mattered to you

once your throttle is open you still need to rev up. If you want your throttle to open faster, stomp on the gas pedal faster...

just trying to open up some horses my car feels delayed when I hit the throttle like the brakes are on then someone let off of them. It has original clutch with 119k on it so I am putting a new performance one in it along with a lighter flywheel but I am just trying to make it more driver friendly. If I wanna pass someone I have to wait a tick for it to get into higher rpms to do so and its annoying. Any input is appreciated and thanks for the input on the other topics
