Are throttle body spacers bad for your car?

Not really, unless the car is equipped with throttle body injection. A spacer helps the air and fuel mix more thoroughly, and it is very popular among carbureted engines. the spacer doesn’t effect anything if the fuel is injected after it, through either port or direct injection.

Do throttle body spacers do anything?

The throttle body spacer permits more air than usual to go into the engine. Thus, the engine does not have to work as hard in order to get the correct amount of air into the combustion chamber. One of the main benefits of a throttle body spacer is an increase in horsepower.

Do throttle body spacers increase gas mileage?

Fuel economy improvement from a throttle body spacer alone would be minimal, especially when towing. They will improve the performance of an engine which can help and hurt fuel economy. If you are typically an aggressive driver, improved engine performance will actually hurt your fuel economy.

Do throttle body spacers need a tune?

Throttle body spacers do not affect overall performance or delivery of air / fuel. Since these spacers have little bearing on performance, a tune is not required after installation.

Can you use a throttle body spacer with a cold air intake?

Expert Reply: The Airaid PowerAid Custom Throttle Body Spacer # AR450-638 that you referenced should work just fine with the cold air intake system you have installed on your 2011 Ford Mustang. It will add about an inch to your intake track length which your cold air kit shouldn’t have a problem accommodating.

How much HP does a throttle body add?

In addition to increasing acceleration performance, larger throttle bodies can also boost overall horsepower. This gives the engine increased power and torque, which may be helpful in situations such as towing. Commonly, adding an aftermarket throttle body can increase engine power by 15 hp to 25 hp.

Do throttle bodies increase horsepower?

Gains from a throttle body can be dependent on modifications. Generally speaking, anytime a throttle body is added, there will be some added horsepower. The amounts can range from 5-25 HP depending on what other modifications are done to the engine.

Is a bigger throttle body better?

A larger throttle body delivers air at a higher rate than a stock engine, allowing the driver to feel an accelerating response from the vehicle sooner. In addition to increasing acceleration performance, larger throttle bodies can also boost overall horsepower.

How do I choose the right size throttle body?

The general rule is: the bigger the size, the higher the RPM needed for a kick of power. If your new throttle body is too big your vehicle will feel tired at lower RPMs, while really taking off powerfully at higher RPMs (when the engine’s demand of air flow matches up with the the internal bore’a bigger size).

Is throttle body porting worth it?

Yup, throttle response alone is worth it. Most people claim a few horsepower gain, but you’ll realistically never feel it, even with a finely-tuned butt dyno. The ported throttle body reduces the time between your foot rolling into the throttle and the engine actually going, noticeably so.

How much HP does ITBs add?

For example, there are bigger block American cars that can run an ITB setup and make close to 100 horsepower while smaller four-cylinder engines could make closer to 30 to 50 horsepower at the wheels.

Do throttle body spacers actually do anything?

A throttle body spacer is a component added to the throttle body of a fuel injection engine to improve fuel efficiency and add power to the engine. The throttle body has a similar function to the carburetor on a non-fuel injection engine.

Does a throttle body spacer really work?

Throttle body spacers can work in some applications; all engines are different, and it’s not impossible that the additional plenum volume could help to compensate for a deficit from the factory. So you may see a bit more horsepower and midrange torque, depending on the car.

Does a throttle body spacer really help?

One of the main benefits of a throttle body spacer is an increase in horsepower. Ultimately, the spacer increases the air velocity which causes an increase in atomization. Also, the spiral flow that results from a throttle body spacer offers much better combustion.

Does a throttle body spacer really do what it says?

Throttle Body spacers don’t do anything. Intake spacers are arguably better. They lengthen the intake runners, which is proven to be beneficial in creating torque. That, and after a 4 hour drive, I was able to hold my hand on the upper intake as long as i wanted.
