Can a throttle body spacer improve fuel economy?
Throttle body spacers promise increased performance and improved fuel economy, but if you’re looking at what is essentially a small circular ring of metal and trying to figure out exactly how it’s capable of improving your engine, you’re not alone.
What kind of ring is a throttle body spacer?
While that might not sound like a lot, considering a throttle body spacer is literally a metal ring, it’s pretty impressive. The different shapes of throttle body spacers are where the science starts to become a little more ambiguous.
How is the throttle body of a car controlled?
It is controlled by the throttle which opens a butterfly valve, allowing different amounts of air in during acceleration. If you’re experiencing lack of power or rough idle this may indicate throttle body problems. Your computer may also turn on the Check Engine light and put the car into “limp home mode”.
How to reset throttle body calibration [ step by step guide ]?
Make sure that the accelerator pedal is fully released. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds.
What do you need to know about throttle body spacers?
A throttle body spacer (or riser) installs between the outlet of the throttle body and the rest of the intake system, sort of like a carburetor spacer, but for fuel-injected engines. Typically made of aluminum, nylon, or resin, they add some extra plenum length and volume.

Is there a way to reset the throttle body?
This method is almost foolproof as long as all ECU control parameters are within their normal ranges. Resetting The Throttle Body Calibration (this step is conditional) A Rough Idle or a SES can sometimes be caused by a change in the throttle body position sensor calibration.
