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.

Easy Performance?

Some drivers report that adding a throttle body spacer, with no other modifications or tuning, improves performance by adding a few horsepower, quickening throttle response, or increasing fuel economy.

Large displacement engines and wide-open throttle conditions tend to benefit most consistently from throttle body spacers. If you’ve made other air-hungry modifications to your engine, the expanded plenum volume will also certainly help. Your results may vary, so we recommend talking to other drivers with similar vehicles who have made similar modifications.
