Vacuum Gauges

A Vacuum Gauge can be an important tool for anyone who wants to monitor their engine’s vacuum and compression levels to ensure the engine is performing at optimal levels. Using a Vacuum Gauge is the most effective way to ensure that your engine is not experiencing any air leaks in the system, which could result in rough idling, poor fuel economy, or increased emissions. GlowShift offers electronically and mechanically driven 52mm Vacuum Gauges in a variety of styles that provide compression and vacuum level readings from -30 to 0 inHG.
