Add Some Midrange Punch with a Trans-Dapt Performance Torque-Curve MPFI Spacer
Trans-Dapt Performance Torque-Curve Throttle Body Spacers smooth out airflow into the engine, delivering more air for more midrange torque and improved throttle response.
At part throttle, a negative pressure zone forms on the upper back side of the throttle body's throttle blades. Incoming air gets drawn to it, creating turbulence that slows down airflow into the engine. The Torque-Curve spacers’ unique port design reduces that turbulence and speeds up airflow into the intake manifold. The result is a denser air/fuel mixture which improves midrange power, throttle response, and fuel economy—without the annoying whistle other spacers can cause. The Torque-Curve spacers are available for most popular 1987-2007 Chevy, GMC, Ford and Dodge trucks.
