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. Spacers intended for use the throttle body injection (TBI) have smooth internal bores, while spacers for multi-port injection engines have ridges or grooves. Either type of spacer can also add a distinctive note to the sound of your engine.

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.

Designed to deliver more horsepower and torque, aFe Silver Bullet throttle body spacers make an excellent addition to your vehicle. They're precision-machined from T-6061 billet aluminum to exacting specifications to provide optimal performance. The combination serrated/helix design creates turbulence so that the air/fuel charge is thoroughly mixed for a complete burn. Their specially-designed serrated edge will reduce the whistling sound normally associated with throttle body spacers. The aFe Silver Bullet throttle body spacers increase the volume between the throttle and cylinder, improving volumetric efficiency.

These JET Powr-Flo throttle body spacers use aerospace engineering combined with years of experience. The exceptional design of the bore causes the incoming airflow to actually smooth out and speed up. This creates a type of compacted air-charge that enters through the throttle body and builds pressure in the combustion chamber. This will result in an extensive gain in the midrange power band and an overall increase in fuel economy.

Airaid's PowerAid TBS concept was developed to enhance midrange power, torque, and fuel efficiency. The unique dyno-proven Helix Bore design of the Poweraid throttle body spacers causes a spinning action of the incoming air-charge as it passes through the throttle body. This extremely beneficial air-charge carries all the way into the combustion chamber, producing a super-atomized mixture, which creates tremendous gains in midrange power and overall efficiency—the key element to horsepower success. The aluminum spacers are available in different thicknesses and finishes. Order the kit recommended for your vehicle.
