The Runner Flap Delete (RFD) kit allows for the removal of the restrictive intake flappers from the factory intake manifold on 2.0 TFSI EA113 Engines. The factory intake flappers can be a substantial restriction in modified vehicles.
The runner flaps are individual plates, functioning like a throttle body flap, located within each of the intake manifold runners. However, even when opened to the maximum position, the flaps still represent an airflow restriction.
The runner flap delete system fills the voids in each runner after removing the factory runner flaps.
We highly recommend upgrading your tuning software with our RFD kits in order to maximize performance. Simply removing the runner flaps can cause adverse running conditions during cold start. However through proper ECU recalibrations, the tuner can eliminate this harsh running condition.
