Features 3 radial slots to let out the “woosh” with optimal flow for all OEM DV types

Engineered to operate CEL-FREE!

Alignment holes for ease of installation

Includes pre-installed, captured Viton O-rings, resistant to chemical degradation

INSTALLATION:

Remove Diverter Valve
Place the spacer onto the DV flange r
Re-install your original DV solenoid atop the spacer with the included longer hardware.
The wastegate actuator must be swung out of the way for install. Loosen both screws retaining the wastegate actuator, then remove the one closest to the actuator, allowing the actuator to swing out of the way. This will allow for ease of installation.
