Now, here’s where things get a little tricky. The actual performance gains from a throttle body spacer are often debated and can be highly dependent on the engine and other modifications. Manufacturers will often make bold claims about horsepower and torque increases, but it’s important to take these with a grain of salt. Look for independent dyno tests or reviews that validate the claims. Don’t be swayed by marketing hype; focus on real-world results and reliable information. Remember that the best aluminum fuel throttle body spacers deliver realistic, measurable improvements.
Thickness and Bore Size
The thickness of the spacer affects how much it raises the throttle body above the intake manifold. A thicker spacer can potentially increase intake manifold volume, which might improve top-end horsepower in some engines. However, it can also reduce low-end torque and throttle response. The optimal thickness depends on your engine’s characteristics and your desired driving style.
The bore size of the spacer should match or be slightly larger than the bore size of your throttle body. A smaller bore can restrict airflow, negating any potential benefits of the spacer. A larger bore can potentially improve airflow, but it’s important to ensure that the air/fuel mixture is still properly atomized. Again, research your specific engine and driving needs to determine the ideal bore size.
Ease of Installation
Let’s be honest, nobody wants to spend an entire weekend wrestling with a simple bolt-on part. Look for a throttle body spacer that comes with clear and concise installation instructions, preferably with diagrams or photos. Some spacers may require minor modifications to existing parts, such as longer bolts or slight adjustments to the throttle cable. Knowing this beforehand will prevent frustration and potential delays.
