The AutoMeter Cobalt 52mm mechanical vacuum/boost gauge uses a patented Bourdon tube movement for precise, durable readings without electrical hookup. A simple 1/8" NPT pressure connection requires no wiring; the gauge ships with 1/8" NPT fittings and a nylon line kit. Modern blue through-the-dial LED lighting improves nighttime visibility, making it a reliable instrument for monitoring intake vacuum and boost.
