When it comes to enhancing vehicle performance, enthusiasts often explore various modifications. One such modification that has gained popularity is the throttle body spacer. Priced around $120, many wonder if this simple addition can genuinely increase horsepower. In this article, we will test the five best throttle body spacers available for under $150 and determine their effectiveness.
What is a Throttle Body Spacer?
A throttle body spacer is an aftermarket component that is installed between the throttle body and the intake manifold. Its purpose is to improve airflow into the engine, potentially leading to better combustion and increased horsepower. The spacer works by creating a turbulence effect, which can enhance the mixing of air and fuel.
Benefits of Installing a Throttle Body Spacer
Installing a throttle body spacer can offer several benefits, including:
- Improved Airflow: Enhances the air intake process, which can lead to better engine performance.
- Increased Horsepower: Potentially adds a few extra horsepower, depending on the vehicle and other modifications.
- Better Fuel Efficiency: May improve fuel economy by optimizing the air-fuel mixture.
- Easy Installation: Generally a straightforward installation process that can be done with basic tools.
Testing Methodology
To evaluate the effectiveness of the throttle body spacers, we conducted tests on a stock vehicle. The tests included:
- Baseline horsepower measurements without a spacer.
- Installation of each throttle body spacer.
- Post-installation horsepower measurements.
- Driving impressions and performance evaluation.
