In short, Yes, Silverado throttle body spacers are worth it as they can potentially improve performance, increase horsepower, improve airflow, and enhance fuel efficiency

In this blog, we’ll delve into the benefits and drawbacks of throttle body spacers and help you decide if they’re right for your Silverado.

Are Silverado Throttle Body Spacer Worth It

What is a Throttle Body Spacer?

A throttle body spacer is a small, circular metal component that is typically installed between the throttle body and the air intake manifold in a vehicle’s engine. 

The purpose of a throttle body spacer is to increase the length of the intake manifold, which can result in improved engine performance. 

By increasing the length of the intake manifold, the spacer creates more surface area for air to travel through and mix with fuel, which can lead to better combustion and increased power output. 

Some manufacturers claim that a throttle body spacer can also improve fuel economy and torque output.

Throttle body spacers are generally simple and easy to install, and they are available in a variety of sizes and designs to fit different makes and models of vehicles. 

They are often made of aluminum, nylon, or resin, and they can be found in both smooth and helix-shaped designs. 

Helix-shaped spacers are designed to spin the incoming air charge as it passes through the throttle body spacer, which can increase the velocity of the air and contribute to better performance.

While some people believe that installing a throttle body spacer can significantly improve engine performance, the benefits of using a throttle body spacer may vary depending on the vehicle and other modifications that have been made to the engine.

Benefits of Throttle Body Spacers

Throttle body spacers can improve engine performance by increasing airflow into the engine, which can lead to increased horsepower, torque, and fuel efficiency. 

They work by lengthening the intake manifold, allowing more air to flow into the engine, and reducing air resistance, resulting in improved performance.

Improved Horsepower

One of the main advantages of a throttle body spacer is the potential increase in horsepower. Creating more space for air to flow into the engine can help improve your Silverado’s overall performance.

Enhanced Fuel Economy

Another benefit of throttle body spacers is improved fuel economy. Directing the flow of air into the manifold more efficiently can optimize the engine’s fuel consumption.

Drawbacks of Throttle Body Spacers

Throttle body spacers have both benefits and drawbacks, and it’s important to consider both before deciding to install one.

Some of the drawbacks include decreased reliability, increased engine noise, and lower fuel economy. Additionally, the promised benefits of increased horsepower and torque may not always be realized.

Increased Engine Noise

One potential downside of installing a throttle body spacer is increased engine noise. This may be a concern if you prefer a quieter ride. Reliability Concerns

Another drawback is the possibility of decreased reliability due to the additional component in your engine. It is essential to weigh this factor against the potential performance gains.

Different Types Of Throttle Body Spacers for Silverado

There are various types of throttle body spacers available on the market, each designed to cater to different preferences and performance goals. Here are some common types:

#1. Helix Power Tower Plus Throttle Body Spacer

This type of spacer features a helical design that creates a vortex in the incoming air, improving air/fuel mixture and combustion.

The helix design promotes better torque and horsepower gains while also improving fuel efficiency.

#2. Straight Bore Throttle Body Spacer

These spacers have a simple, straight-bore design without any helical or vortex features.

They work by increasing the plenum volume, which can lead to better throttle response and engine performance.

#3. Venturi Throttle Body Spacer

Venturi spacers have a tapered design, similar to a funnel, that helps to increase the velocity of the air entering the engine. This design can enhance throttle response and overall engine performance.

#4. Combination Throttle Body Spacer

These spacers combine the features of the helix and straight bore designs, aiming to provide the best of both worlds.

They can create a swirling air charge for better combustion while also increasing plenum volume for improved performance.

#5. Swirl Throttle Body Spacer

Swirl spacers are designed with channels or grooves that direct the incoming air in a swirling motion.

This swirling effect helps improve the air/fuel mixture and combustion efficiency, leading to better performance and fuel economy.

Note: Each type of throttle body spacer has its unique advantages and may offer varying levels of performance improvement. It’s essential to research and choose the right type of spacer for your vehicle and performance goals. Always consult a professional if you’re unsure about the compatibility or installation process.

Are Silverado Throttle Body Spacers Worth It?

You already know that the throttle body spacers are worth the money. But, the worthiness of a throttle body spacer for Silverado trucks depends on the performance goals and expectations of the individual owner. Throttle body spacers can provide some benefits, such as improved horsepower, torque, and fuel efficiency.

These improvements are typically due to the spacer increasing the air surface volume and lengthening the intake manifold, which helps optimize the air/fuel mixture for better combustion.

If you are seeking modest performance gains and fuel economy improvements, a throttle body spacer might be worth considering for your Silverado.

On the other hand, it’s important to note that the performance gains from a throttle body spacer can be relatively small and may not justify the expense for some users. 

Additionally, installing a throttle body spacer may result in increased engine noise and the possibility of decreased reliability.

If you prioritize a quieter engine or prefer not to modify your vehicle’s intake system, a throttle body spacer may not be the right choice for you.

Ultimately, whether a Silverado throttle body spacer is worth it depends on the individual’s performance goals, expectations, and personal preferences.


So, is a throttle body spacer worth it for your Chevy Silverado? The answer depends on your priorities.

If you’re seeking improved horsepower and fuel economy, a throttle body spacer may be a worthwhile investment.

However, if you value engine noise reduction and reliability more, it might not be the right choice for you.

Be sure to weigh the pros and cons before making a decision, and always consult with a professional if you’re unsure about installation or compatibility.
