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. Whether you're monitoring boost pressure on a turbocharged application or tracking intake manifold vacuum on a naturally aspirated engine, this dual-range gauge gives you real-time feedback on critical engine conditions. The Cobalt face design combines durability with excellent visibility, making it a reliable choice for both street and competition builds where data-driven tuning decisions matter.

Built by AutoMeter's precision engineering team, this gauge features a 2-1/16-inch diameter dial with a measurement range of 30 inches of mercury (vacuum) to 30 PSI (boost), allowing seamless transition between naturally aspirated and forced induction monitoring. The dual-range design eliminates the need for two separate gauges, saving dashboard space and installation complexity while maintaining accuracy across both pressure bands. A quality movement ensures repeatable readings, and the compact 4.8 x 4.5 x 5.15-inch package (0.63 lbs) integrates easily into custom gauge clusters, pillar pods, or A-pillar installations without adding excessive weight or bulk.

This gauge serves mechanics and tuners working on turbocharged, supercharged, and carbureted applications where vacuum signal monitoring is critical for carburetor function or emission diagnostics. Install it via a simple hose connection to your boost source or manifold vacuum line—no complex wiring required. The robust construction handles vibration and temperature swings common in engine bays, making it ideal for both OEM diagnostic work and aftermarket performance builds where precise fuel mapping and boost control depend on accurate live feedback.
