Are they serious..an increase of 22hp.

I still don't see how you can gain power like that by adding space between the tb and intake.

ahhhhhh. No.

i call bs

we had a similar issue with the motorsyne spacer, the guy form motorsyne even joned int he discussion, basically they add the advertised hp at one point in the powerband, nto at the peak the peak gain is actually a fraction of that it just smoothes out a dip the the power band a bit

i have that exact TB spacer on mine. Gave me like 250 hp. don't know what gains i got from it, but i put it on before everything else i have on the intake and it felt a little different. Probably felt better MPG's! lolI know TB spacers on other cars and trucks make a difference in power and fuel usage, but whether its 2 or 22 i don't know.I probably wasted my money because i ended up getting the Injen CAI and Kinetix V+

i just want to scientifically know what "THEIR" version of proof is, cause i know some of the silly stuff like the "turbonator" and the one "exhaust tip fan" thing where so hillariously wrong.

As taken from a resource for Toyota trucks:

Designed to be installed between your truck’s throttle body and its intake, these devices, such as the PowerAid made by Airaid, claim to be able to create an intense ‘vortex’ of air which will help better atomize fuel when the two are mixed together. According to the manufacturers, this is accomplished by a series of grooves which are carved inside the device itself.

Unfortunately, there are some flaws behind the engineering in this device. From a common sense perspective, if it were really that easy to add significant amounts of horsepower or fuel mileage gains, then these spacers would be stock equipment from the factory. Automakers need every competitive edge they can get in today’s market (especially when it comes to fuel economy) and none of them are leaving anything on the table in that area. The idea that a ‘vortex’ could help the air and fuel mix together is not a bad one, but in the modern fuel injected engine air and fuel are not mixed together until they both find themselves in the cylinder [correction] air and fuel are mixed together inside the intake manifold, relatively far away from the throttle body prior to combustion.

In primitive forms of fuel injection (such as throttle body injection), where fuel was sprayed directly at the throttle body and then mixed with the air immediately before being routed to the cylinders, then perhaps a spacer would be of some benefit. Spacers can also help generate power on carburetted engines. However, the technology used in the Tundra’s multi-point fuel injection system precludes any useful effect from such a device. The chances that the air would still be feeling the effects of a vortex by the time it got through the intake to the cylinder are very low.

Bottom Line: We do not endorse the use of a throttle body spacer on any modern fuel injected engine. Save your money and put it towards something else. A K&N performance air filter, for instance, costs half as much and it will definitely improve your engine’s performance and fuel economy.

They don't work.

lol, I didn't bother clicking the link, I thought it was like the plenum spacer, yeah garbage
