The new Edelbrock 1-Bar Manifold Absolute Pressure (MAP) Sensor #36021 is designed to fit Chevrolet LS3 applications that use an Edelbrock LS3 XT intake manifold or any other factory-style intake that has a 12mm MAP sensor port hole. This 1-Bar MAP Sensor #36021 should also replace the 1-bar MAP sensor on factory LS3 applications when an Edelbrock Pro-Flo 4 EFI System has been installed in order to provide a compatible calibration during installation and tuning.
