Performance throttle bodies are a direct replacement for factory throttle bodies and are designed to produce more horsepower, provide improved throttle response, and increased airflow over stock units. Performance throttle body spacers allow a greater amount of air to flow into your throttle body for increased power. This greatly improves torque and horsepower while creating more combustion and an efficiently burning engine which results in improved fuel economy. Whether its a throttle body or throttle body spacer, let AutoTruckToys help you upgrade your GMC Sierra to a better performing and more reliable version.
