Mighty Mouse LT4/LT5 Valley Plug with 1/8 NPT Port
This part replaces the factory pcv valve stopping airflow (and oil) into the floor of the supercharger on gen V LT4 AND LT5 DI engines (2015+ Z06, Camaro 6 ZL1, and Cts-V)
'Plug' version seals this path off entirely
'Port' version re-routes the crankcase flow to the outside of the engine, so that it can be used for external ventilation.
