Dial in part-throttle ignition timing with the Standard Ignition Distributor Vacuum Advance VC-498. It drops in as a direct-fit replacement for the 1982 Nissan Sentra (L4-1.5L), restoring the vacuum-operated advance function of your original unit.
A distributor vacuum advance is a vacuum-actuated diaphragm that reads engine vacuum and rotates the distributor breaker plate to advance ignition timing under light-load, part-throttle conditions. If a leaking or worn advance unit is the cause of hesitation, pinging, or poor part-throttle economy, this replaces it.
Precision calibration: set to help ensure correct ignition advance.
Leak-tested: units tested at 30 HG maximum vacuum to confirm they do not leak.
Two hose connectors: the vacuum control has 2 hose connectors.
Trusted supplier: from a manufacturer serving the automotive aftermarket since 1919, with quality control maintained from componentry to finished product.
