Detailed Description

Standard Ignition PVS166 is engineered as an OE-style ported vacuum switch for vehicles that rely on precise vacuum signal routing for emission control operation. The brass and heat-resistant plastic housing supports durability in underhood conditions, while the thermal design helps the switch respond consistently as temperatures change.

This part cross-references Standard Ignition 2-29221 and E9073 for the same application.
