2-1/16in C/S Boost/Vac Gauge 30in Hg/30psi

The AutoMeter 2-1/16in C/S Boost/Vac Gauge (Part Number 6103) is an essential diagnostic and tuning instrument for serious engine builders, turbo enthusiasts, and performance mechanics. This dual-range gauge provides real-time feedback on critical engine conditions, making it ideal for monitoring boost pressure on turbocharged applications or tracking intake manifold vacuum on naturally aspirated engines.

Featuring a durable Cobalt face design for excellent visibility, this gauge has a measurement range from 0 to 30 inches of mercury (vacuum) and from 0 to 30 PSI (boost). The compact 2-1/16-inch diameter dial integrates easily into custom gauge clusters, pillar pods, or A-pillar installations without adding excessive weight or bulk. A quality movement ensures repeatable readings, enhancing the reliability of your tuning decisions.

This gauge is particularly beneficial for mechanics and tuners working on turbocharged, supercharged, and carbureted applications where vacuum signal monitoring is critical for carburetor function or emission diagnostics. Installation is straightforward via a hose connection to your vehicle's boost or vacuum source, making it a versatile addition to any performance setup.
