The CMS Runner Flap Delete System (RFD) 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.

The CMS RFD System fills the voids in each runner after removing the runner flaps. Each piece is precision CNC machined from billet aluminum.

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 Stage 2+ and higher modified engines.

Creations Motorsport was founded in 2007 by a group of VAG enthusiasts in Germany. The company started life as a hobby which turned into something much bigger. CMS is known around the world for their brake adapters and other unique solutions for VW/Audi models. Braking components are taken very seriously and every brake adapter is track tested before it is put into production. All components are machined in-house at their Birmingham, United Kingdom facility.
