The APR Runner Flap Delete (RFD) System is a motorsport inspired upgrade designed to eliminate airflow restrictions within the factory intake manifold. This product is for anyone looking to maximize performance on highly tuned engines. The runner flaps are individual plates, much like a throttle body flap, located within the intake manifold runners. Unfortunately even when opened to the maximum position, the flaps still represent an airflow restriction.
Simply removing the runner flaps can cause adverse running conditions during cold start. However through proper ECU recalibrations, APR's able to provide RFD specific software for all APR software stages to eliminate this harsh running condition. This is a free upgrade for all existing APR ECU Upgrade customers with this purchase.
Power Gains: At Stage 3 airflow levels, typical results showed a decrease in turbocharger lag, more than a 10 ft-lbs. of torque gain and more than a 10 horsepower gain.
Recommendations: This modification is recommended for APR Stage 2+ and higher modified engines.
Application: For all 2.0T FSI (EA113) factory intake manifolds. If you're unsure which you have, please call for assistance.
