ZZPerformance Throttle Body Spacers

ZZPerformance throttle body spacers are designed to create a wider space between the throttle body and intake manifold, allowing for a larger volume of air to flow into the engine. This increased airflow can theoretically lead to a slight increase in horsepower and torque, particularly in the mid to high rpm range. Spacers intended for use with the throttle body injection (TBI) have smooth internal bores, while spacers for multi-port injection engines have ridges or grooves. Type of spacer can also add a distinctive note to the sound of your engine. Some drivers report that adding a throttle body spacer, with no other modifications or tuning can help improve performance by adding more horsepower and torque, quickening throttle response, or increasing fuel economy. The throttle body spacers are made from billet aluminum and include the necessary hardware needed for a proper installation.
