Slide Valve MFI Injection System 911 / 914-6 1970-89 - 43mm Valves

This German made replica of the 1974 RSR 3.0L slide valve injection system keeps air consistently on tap for superior drivability. When the throttle is opened, there is an instant injection of air, providing a sharp, crisp throttle response. This efficient injection frees up more power and compliments larger displacements, high lift cams and full exhaust systems. This kit is engineered, precision machined, flow tested and manufactured in Germany. It is replicated to look as close to the original as possible.
