Mazdaspeed 3/6 VTCS Delete

$75.00

Mazdaspeed VTCS Delete Kit

Simplify your intake. Free your airflow. Unlock more power.

The VTCS Delete Kit is designed to remove the bulky, restrictive Variable Tumble Control System (VTCS) from your Mazdaspeed intake manifold—eliminating the black plastic actuator box, internal flaps, and unnecessary valves that choke your engine’s airflow.

Whether you're cleaning up your engine bay or chasing peak performance, this mod is a smart move for any serious Mazdaspeed enthusiast.

✅ Key Benefits

  • Cleans Up the Engine Bay – Say goodbye to the cluttered plastic actuator box and control rods.

  • Improves Airflow – Removes turbulence-causing flaps and valves inside the runners.

  • Boost-Ready – Includes a 90° barb fitting to use the port as a boost reference.

  • Performance Gains – Reduces restriction at high RPMs, enhancing throttle response and cylinder filling.

  • Flexible Setup – Use the supplied plug for a clean delete, or repurpose the port for accessories like a boost gauge or FPR.

🔍 What’s Involved

This delete involves removing:

  • The VTCS actuator (black box)

  • The metal plunger and shaft on the side of the manifold

  • All flaps and valves inside the intake runners

  • Associated vacuum lines and electrical connectors

You’ll gain a smoother, more direct path for airflow—exactly what your engine wants when you’re pushing power.

🛠️ Installation Tips

  • Leave the black rubber grommet in the intake manifold to maintain a proper seal.

  • When removing the internal flap rod, ensure no internal seals or bushings are dislodged.

  • Check the gasket at the intake manifold; replace if worn to avoid leaks.

  • Remove the throttle body and cold pipe for easier access during install.

  • Block off any unused ports to prevent vacuum leaks.

  • Don't forget to remove center bolts on the manifold for full removal.

📝 Pro Tip: Consult your service manual for exact torque specs and removal steps.

👨‍🔧 Who This Is For

  • Mazdaspeed 3/6 owners who want cleaner airflow and improved performance

  • Builders looking for a boost reference port for gauges or regulators

  • DIYers cleaning up the engine bay for a more aggressive, track-ready setup

  • Tuners chasing smoother high-RPM performance

📣 What Enthusiasts Are Saying

“Noticeably better throttle response above 4k RPM.”
“Install was straightforward, and the engine bay looks way cleaner.”
“Makes a great port for a boost gauge or external fuel pressure reg.”

⚙️ Included in the Kit

  • 1x VTCS delete plug

  • All necessary hardware for install

Take the guesswork out of your build. Ditch the VTCS. Gain power. Clean up your manifold.
