Gen3 Coyote CMCV removal: Why remove the CMCV valves

Tight engine bay with A/C

First, the engine bay will be insanely tight with the A/C setup.

So I decided on Gen3 Coyote CMCV removal.

In other words, I pulled the CMCV valves off the intake back.

What is the CMCV?

Meanwhile, the Gen3 Coyote has rear intake actuators.

They are called Charge Motion Control Valves.

Also, they control short and long runners in the intake.

Then they add some torque in the lower RPM bands.

After that, they open up for upper-RPM runs.

However, that suits everyday Mustang or F-150 drivers.

Still, in the Cobra they will not change much.

Because the car has to be tuned anyway.

Notice the ‘snails’ on the back of the intake.

Those are the CMCVs.

Removal steps and locking open

Space savings

Next, the CMCV valves take about five inches at the back.

As a result, they steal a tremendous amount of space.

However, removal is simple.

First, remove six T-20 screws.

Then remove two circlips.

After removing these valves, lock the runners open.

Because that allows maximum airflow.

Billet plates instead of zip ties

Some builders use zip ties to lock the runners open.

However, I opted for some $15 billet plates.

Also, the billet plates fit perfectly around the lever.

Then the circlips hold that lever area.

Ultimately, the other billet end reuses a T-20 screw.

Besides that, this Gen3 Coyote CMCV removal frees bay space.

So the A/C path looks much more workable.
