A distributor vacuum advance control uses engine vacuum to move ignition timing ahead under light-load conditions, then lets timing return as vacuum drops. If a leaking or sticking original unit is the cause of sluggish part-throttle response or poor fuel economy, this unit replaces it.
- Precision calibration: Calibrated for correct ignition advance.
- Leak tested: Units are tested at 30HG maximum vacuum to confirm they do not leak.
- Quality control: As a global manufacturer of original equipment ignition products, Standard keeps quality control in-process from componentry through to the finished product.
- Heritage: Standard has served the automotive aftermarket since 1919, focusing on quality and broad ignition coverage.
Signs this part may need replacing include a diaphragm that will not hold vacuum, a hiss at the unit, hesitation or flat response at part throttle, or reduced fuel economy. Diagnose the cause before replacing, since timing and vacuum problems can have other sources.
