This bosch GM LS3 Manifold Absolute Pressure (MAP) sensor is designed to direct fit into VE/VF Holden Commodore & HSV LS2 LS3 engines. This sensor is used to determine engine load on forced induction engines. This sensor is a popular upgrade intended to be used on engines producing positive manifold pressure up to 1.9 BAR, or roughly 28psi of boost. It can also be used for universal applications that also require a map sensor up to 1.9 BAR. Replaces 0261230262.
