See the Buyer's Guide tab for the full list and engine details.
A vacuum advance unit uses engine vacuum to move the distributor's ignition timing ahead during light-load, part-throttle driving. The timing moves back as vacuum drops. Standard Ignition lists these features for VC-190:
- Precision calibration: Calibrated for correct ignition advance.
- Leak-tested: Units are tested at 30HG maximum vacuum to confirm they do not leak.
- Controlled production: As a global manufacturer of original equipment ignition products, Standard Ignition keeps complete quality control over the manufacturing process, from componentry to finished product.
- Ignition heritage: Standard Ignition has served the automotive aftermarket since 1919, with a focus on quality and broad coverage for ignition needs.
Signs this part may need replacing include hesitation or sluggish response at part throttle, reduced fuel economy, or an advance unit that will not hold vacuum. Other faults can cause the same symptoms, so check the vacuum source and ignition timing before replacing. If a failed vacuum advance is the cause, VC-190 replaces it.
