Runner Flap Delete (RFD) for FSI engines including Golf R models. The Runner Flap Delete allows for the removal of the restrictive intake flappers from the factory intake manifold. The factory intake flappers can be a substantial restriction in modified vehicles, the RFD is a must for any FSI owner that wants to minimize airflow restrictions and maximize power to the ground. We highly recommend upgrading your tuning software with our RFD kits in order to maximize performance.
