Can a throttle body spacer damage your engine?

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.

Where does the air go in a throttle body spacer?

When an individual cylinder’s intake valve opens, it’s going to pull a massive chug of air from the vortex. That air goes into the intake runner, where it establishes a boundary layer on the walls and flows through as it normally would.

How does the throttle body work in a car?

So, essentially the throttle body’s purpose is one of the most crucial in the continued functioning of your engine. Whether it’s a carbureted or fuel-injected engine, your throttle body permits air to enter and either via pressure vacuum or sensor, tells it how much fuel to inject.

Why do you need a body spacer for a carburetor?

Carburetor spacers have long been the go-to solution for the plenum-volume problem, and they’re known to add horsepower and torque in many applications. The plenum acts as a sort of air reservoir for the cylinders, ensuring that the runners always have oxygen on tap regardless of rpm.

What are the advantages of laminar flow throttle?

Laminar-flow proponents claim that smoother airflow through the throttle body enhances net flow. We’ll see. Air flowing into an engine doesn’t just flow straight through in one big mass.

How do throttle body spacers and variable intake manifolds work?

Variable intake manifolds and throttle body spacers actually have a few similarities in that regard, including that some throttle body spacers claim to work by increasing turbulence.

Is it worth it to use throttle body spacers?

Despite the fact that dynos and drivers both report seeing power improvements, it’s tough to believe that throttle body spacers can be capable of that kind of improvement given their simple design. Understanding how these modifications function can help you determine whether or not it’s likely to improve your car meaningfully.

How many valves does a throttle body have?

Depending on your vehicle, the throttle body can look very different. Some vehicles have many throttle bodies or a throttle body with two valves. Most vehicles will have one large throttle body.
