I'm unclear on why simply dropping a spacer in would increase your power. Is it because the spacer helps reduce heat transfer into the TB? That might lower the intake air temp and increase it's density. Am I anywhere near right?

It doesnt do anything. DO NOT waste your money. The only thing they are good for is a place to port for meth injection.
this all started with carbed cars. they put these under the carb and it would help increase turbulence forcing the air and gas to mix better. it will do NOTHING on a fuel injected car with fuel injectors in each intake port. on top of all that the factory intake is plastic so it transfers no heat to the TB

It does work, I have a friend with a Mazda 6- he installed it and his fuel ecnomy went up a bit and throttle responce is better. Also when driving it sorta makes a sound like a turbo, just a bit.
He has not done a Dyno, but the before and after feel can be felt, you know the Seat of the Pants DYNO!!! :lol:
not trying to put you down, but there have been dyno tests that prove no gains whatcoever. You cant "feel" a 2-3 hp increase. You were right about the butt dyno...thats all it is. Fuel economy can change drastically just on driving habbits, so again it shows nothing.
The basis behind the design of these spacers is they say that threadlike shape of the inside makes the incoming air mix better with the fuel. This doesnt happen since the air still has to travel through the intake manifold and then through the valves.
The spacer is about as useless as that vortex shettmetal POS you can stick in your intake to "give you better gas mileage"
if you want you car to sound like a turbo....then get a turbo. Please. please, please, dont waste your money. There are plenty of other relatively inexpensive mods you can do, that will actually give you gains.
