APR MS100033 Manifold Runner Flap Delete Audi and VW 2.0T FSI
You save: $14.05
The APR MS100033 Runner Flap Delete (RFD) System is a motorsport inspired upgrade designed to eliminate airflow restrictions within the factory intake manifold on highly tuned FSI 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 which can rob HP on stage 2+ to 3+ tuned engines. The APR RFD System fills the voids in each runner after removing the runner flaps.
Simply removing the runner flaps can cause adverse running conditions during cold start. However through proper ECU recalibrations, APR is 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, and a gain of 10 HP / TQ.
APR MS100033 Runner Flap Delete Vehicle Fitment:
Recommended for stage 2 and higher tune levels
APR MS100033 Flap Delete Manufacturing: Each piece is precision CNC machined from billet aluminum on APR's live tooling in house lathe.
