APR 2.0TFSI Runner Flap Delete Kit
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 maximise 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 as illustrated in the graphic.
The APR RFD System fills the voids in each runner after removing the runner flaps. Each piece is precision CNC machined from billet aluminium on APR‘s live tooling in house lathe.
Simply removing the runner flaps can cause adverse running conditions during cold start. However through proper ECU recalibration, 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.
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.
