Do throttle body spacers actually work?


Sharing is Caring


An additional test was run after removing the spacer, resulting in a return of the lost horsepower. Proving that some spacers can actually rob power from an engine. After seeing the results, it was clear that throttle body spacers were simply gimmicks and provided no real performance value.

How much HP does a throttle body spacer add?

When you add a throttle body spacer to your car, it can increase its performance by adding up to 18 more horsepower. The torque might also increase by 25ft-lbs, increasing the performance and minimizing fuel consumption.

Do you need tune after throttle body spacer?

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.

Does a throttle body spacer help throttle response?

The Benefits of Throttle Body Spacers You’ll see an increase in horsepower and torque when you add a spacer. Throttle Body Spacers can also benefit: throttle response. fuel economy & fuel mileage.

Do throttle body spacers increase gas mileage?

A throttle body spacer is an easy bolt-on upgradeโ€”it fits between the throttle body and the intake manifold. Most designs either speed up or impart a swirl action to incoming air to increase its velocity. That helps improve low and midrange power and fuel mileage.

Do throttle body spacers work on direct injection engines?

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.

Is a throttle body upgrade worth it?

Another benefit to adding a larger throttle body to your car’s engine is that any other modifications that you add will make more power too. Since you’re adding more airflow, other power adders like a supercharger, turbocharger, or even simple bolt-on parts will make more power as well.

How much power does a cold air intake add?

Cold Air Intakes are said to improve your vehicle’s performance by 5-20 horsepower. This number will vary depending on the make and model of your vehicle. While this isn’t enough power to put you back in your seat, it will give your car or truck a little pep in its step.

Do throttle controllers really work?

Do throttle controllers really work? Yes, a throttle controller works to remove throttle lag and works great! An electronic throttle control changes how your car’s engine control unit (ECU) reads input from your gas pedal and the rate at which that throttle input is applied to the engine.

What is a throttle body spacer good for?

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).

Should I clean the throttle body or replace it?

Generally, throttle bodies do not need to be replaced completely, but rather just need specific parts related to them replaced. I would also recommend checking the mass air flow sensor to be sure it is functioning correctly as well since this could also cause the car to hesitate or run poorly.

Are throttle body spacers legal in California?

Although most throttle body spacers are generally guaranteed street legal, check with the manufacturer to get specific approvals for this engine add-on. In California, many of the throttle body spacers on the market are also approved by the California Air Resource Board according to emissions controls.

How do you install a throttle body spacer?

What is a ported throttle body?

A ported throttle body is intended to optimize air flow and promote air velocity which will provide benefits on any engine, but if the throttle body is too small, it will still be a choke point.

Does removing catalytic converter improve gas mileage?

Removing a catalytic converter will not improve MPG. However, replacing an old or clogged one will. Catalytic converters do not affect gas mileage unless they are not working correctly, so removing one will not make a difference unless it wasn’t working correctly, to begin with.

Does increasing horsepower increase mpg?

A high level of horsepower in automobiles is useful in applications such as high-speed racing. But under typical driving conditions for family automobiles, using high horsepower uses more fuel.

Does a better exhaust improve MPG?

Because exhaust gasses can exit the vehicle more quickly than they could with a default factory muffler, backpressure to the engine is all but done away with and the wasted energy in the exhaust system is reduced. All of this results in better gas mileage for your vehicle.

What can I use to clean the throttle body?

YouTube video

How does a throttle body work?

A throttle body is a butterfly valve located between the air intake filter and the intake manifold. It regulates how much air can go into the engine, based on driver input through the gas pedal. As more air flows into the engine, it injects more fuel, thus allowing for more power.

What does a spacer under a carburetor do?

Spacers are said to improve air/fuel vaporization through and out of the carburetor. Anytime the air/fuel charge has to turn sharply coming off the carb, it increases the chance of separating the fuel from the air.

Will a throttle body void my warranty?

A ported throttle body will not void your warranty. The dealer would never even notice it’s ported.

What does a bigger intake manifold do?

The stock intake manifolds on most model mustangs are designed to be more functional than powerful. They are designed to get consistent results, and to be cost effective for production. Upgrading your intake will not only increase horsepower, it can also change the rpm range at which the most horsepower is created.

How much is a throttle body?

The average throttle body replacement cost is between $250 and $650, depending on the car model and labor costs. The throttle body cost between $200 and $500, while the labor cost is around $50 and $150. The throttle body can be differently priced depending on different vehicles, models, and the manufacturing company.

Do you need a tune with a cold air intake?

Yes. To put it simply, anytime you modify the airflow in an engine you will need a custom tune to compensate for the change. There are intakes that don’t modify the airflow enough to where you need a custom tune so identifying which one you have is important.
