Mazdaspeed3 / Mazdaspeed6 VTCS Delete Kit
Clean up your intake manifold and remove unnecessary airflow restriction with the GGP Mazdaspeed VTCS Delete Kit. This kit is designed for 2007-2013 Mazdaspeed3 and 2006-2007 Mazdaspeed6 models equipped with the 2.3L DISI Turbo engine.
The factory VTCS, or Variable Tumble Control System, uses internal flaps, shafts, and an external actuator assembly inside the intake manifold. While this system was designed for factory operation, many Mazdaspeed owners remove it when cleaning up the intake manifold, improving airflow path consistency, or building a more performance-focused setup.
Removing the VTCS components helps create a cleaner, more direct airflow path through the intake manifold while also eliminating the bulky actuator box and related hardware from the engine bay.
Key Benefits
Removes the factory VTCS flaps, shaft, actuator, and related hardware
Helps improve airflow through the intake manifold
Cleans up the engine bay
Reduces intake manifold clutter
Useful for performance builds, intake manifold refreshes, and custom setups
Can provide a cleaner boost reference option depending on setup
Great supporting modification for modified Mazdaspeed3 and Mazdaspeed6 builds
What This Kit Does
The VTCS delete removes the restrictive internal flaps and hardware from the factory intake manifold. This helps reduce airflow disruption inside the runners and gives the engine a smoother, cleaner path for incoming air.
This is a popular modification for Mazdaspeed owners who are already removing the intake manifold for cleaning, porting, EGR cleaning, injector service, or other performance work.
Installation Notes
Intake manifold removal is required.
Remove the VTCS actuator, metal shaft, internal flaps, and related vacuum components.
Leave the factory rubber grommet in place when needed to maintain a proper seal.
Inspect the intake manifold gasket during installation and replace it if worn or damaged.
Block off unused ports to prevent vacuum leaks.
Verify all hardware is secured before reinstalling the manifold.
Tuning may be required to prevent VTCS-related check engine lights depending on your setup.

Important Notes
This kit is designed for the factory Mazdaspeed intake manifold.
Professional installation is recommended if you are not comfortable removing and modifying the intake manifold.
Always verify vacuum routing, boost reference routing, and manifold sealing before driving.
