VTCS Delete
VTCS Delete
Mazdaspeed VTCS delete gets rid of the ugly black plastic box on top of your intake manifold, the big plastic plunger on the side of the intake manifold and the flaps inside the runners of the intake manifold.
This can be used with the supplied plug to simply delete the VTCS or you can use the supplied 90 barb fitting and use it as a boost reference for stuff such as a boost gauge or fuel pressure regulator.
When taking the factory system off make sure to leave the black rubber grommet in the top of the intake manifold in the hole so the new part will seal, and that no seals come out when pulling the rod the flaps used to be bolted to out of the side of the intake manifold.
An updated tune file will be required to get rid of the CEL associated with deleting the VTCS
