Fine-tune part-throttle ignition timing with the Standard Ignition Distributor Vacuum Advance VC-373. This vacuum-operated diaphragm unit mounts on the distributor and shifts ignition timing in response to engine vacuum, adding spark advance under light-load, part-throttle conditions. It drops in as a direct-fit replacement for the 1980 Toyota Tercel (L4-1.5L). If a leaking or seized vacuum advance on your Tercel is the cause of poor part-throttle response, this replaces it.

  • Precision calibration: calibrated to deliver correct ignition advance.
  • Leak-tested: each unit is tested at 30 HG maximum vacuum to confirm it does not leak.
  • Three hose connectors: built with three hose connectors for its intended vacuum routing.
  • Trusted ignition source: from a manufacturer serving the automotive aftermarket since 1919 with in-house quality control from componentry to finished product.

Diagnose the cause of a timing or driveability concern before replacing, since these symptoms can have other sources. Country of origin: Japan. Available only while supplies last.
