Need an intake vacuum EGR TVS replacement? Replace it with the C3 Corvette 1974-1982 Intake Vacuum Switch from Corvette Mods.
The Corvette EGR TVS mounts right into the intake manifold. As a thermal vacuum control switch, this controls vacuum to the EGR valve. If you are experiencing surging or rough idle, this switch could be the culprit.
Don't sacrifice your EGR TVS when you can get an affordable replacement that will have your Corvette up and running again.
