Cold Air Intake w/ Throttle Spacer

[leesdawgs]

since everyones still talking about this TBS, I have one for an 04 V8 and am looking to get rid of it. I never got to put it on because I have an 05 and was told it would fit and now no one can help me....

I would like to find one for an 05, if anyone out there knows anything please let me know....

I would figure if a TBS worked then why wouldn't Toyota already incorporate a piece like that since MPGs are a big priority with new cars and government regulations. I've seen dyno results right in front of my eyes on three 3.4L engines and the TBS showed no changes to horsepower or torque and new engines aren't like old carbed engines. People who buy this like thinking they are getting something for minimal money.
I guess the Tornado aluminum thingy works too.

I wish I invented something that's proven worthless but people will still shell out the cash to buy it.

I persoanlly don't care what people spend their money on but I'd like to see my fellow car/truck enthusiasts make and educated purchase instead of going by a popular opinion.

The injector is mounted towards the Intake valve. There is a swirling effect of the

Being a mechanical engineer, I can't help but wonder how air, passing through the TBS, through what look machine threads (see picture), is supposed to "swirl" ESPECIALLY!!!!!!! at high velocity (e.g., WOT). Who can explain this?

Now, the "piece-o-work" Tornado, in the middle of the air flow would have no choice but to twist the air, so that at least, makes some sense.

Unfortunately, I bought this TBS before I researched it (I was just excited to see something else for an '04 V6 T4R) and now it's sitting on my dresser, uninstalled and brand new. I'd like to get rid of this piece of aluminum because the only reason I'd put it under my hood is to add some color (in this case, red). Since my hood is closed 99.99999% of the time, I don't care for the addition of a red piece of metal...if it was blue, maybe.

If somebody can PROVE that it adds even a couple of hp or foot-pounds, I'd like to retract most of this reply. If not, give me a hollar and I'll send it to you for $100...including S&H.

Sincerely,
Mr. Impulse Buyer

Ahh, I see I replied a year later...That's great.

It's ok,I think more and more people are realizing TBS are worthless especialy on a direct port injection modern engines where the fuel and air aren't ever mixed til the combustion chamber thus rendering any swirling of the air prior is useless but I sure wish i invented it since there's plenty of suckers out there.

There must be a reason why EVERY car manufacturer these days on almost all regular sedans and SUV's make use of the closed airbox/panel air filter. You would think that if there was truely a better way to get more fuel economy/power, which car manufacturers are doing everything they can do to get it, such as this TBS or a cold air intake, then they would have done it on all vehicles these days. The simple fact is that the closed airbox design is basically a stock cold air intake on its own because it draws air from the wheel well, this has obviously been determined by MANY car manufacturers for MANY vehicles they carry, for both simple maintenance, that stock airboxes are the most efficient, quiet, safe, and easy to maintain of all possible air intake designs.

Using one example I've noticed where a manufacturer uses an open element cone filter is just about every performance package you can buy for a new mustang (Shelby Cobra, GT Hertz, Boss) uses an intake like this. Yeah, its not a truck, but the factory warranty is still valid with the use of these filters on the mustang. This is mostly performance based, but I noticed better gas mileage on my 4Runner after installation...

The airbox with the panel filter is simply the cheapest, easiest compromise for a manufacturer between durability/dependibility and performance and/or fuel economy.

Very true. My old car a 2002 Mercedes C32 AMG made use of a dual short ram air intake for the superchargers, however this is far from a "normal" run of the mill sedan/SUV/truck as is the Hertz mustang, shelby cobra, ect. And I completely agree that the closed airbox design is a compromise, because car manufacturers must be able to make their cars versatile for all environments, whether it is dirt road/dusty desert driving, salty air coastal driving, fording rivers, or regular city driving. Running the stock airbox will allow you to do well in all situations, where a vehicle with an open element will run a risk in certain situations. If you drive all in city and arent running through waist deep water, I am sure you will be OK as you are outrunner.

And let's not forget that the TRD CAI is a closed box design that pulls air from the wheelwell...

You also have to realize that the closed air box design is also designed to be the quietest possible. Many people don't want to hear a roar from their car coming from the exhaust or intake, so take that into consideration. Todays cars are not formed for total performance, they are formed to be quiet, efficient, and produce less emissions while still having decent power.
