2-1/16in C/S Boost Gauge 0-35 psi

The AutoMeter 2-1/16in Cobalt Boost Gauge (0-35 psi) is a mechanical, analog pressure instrument designed for engine management systems requiring real-time boost monitoring. This boost gauge delivers accurate readings across the 0–35 psi range, making it suitable for naturally aspirated and moderately boosted engine applications. The 2-1/16-inch diameter face fits standard dashboard pod installations, while the black dial face ensures legibility in varying light conditions.

Mechanical gauges like this AutoMeter model operate independently of engine electronics, eliminating the need for external power or sensor calibration. The analog needle responds directly to manifold pressure changes, giving drivers immediate tactile and visual feedback on boost levels. A 0–35 psi range accommodates supercharged and moderately turbocharged setups without excessive needle swing, preserving reading precision across the operating envelope. The gauge's compact 2-1/16-inch format integrates into most aftermarket and OEM pod clusters without modification.

This boost gauge is ideal for engine builders, forced-induction enthusiasts, and performance tuners who need dependable pressure monitoring without electronic complication. Drivers building carbureted supercharged engines, turbocharged platforms, or blower-equipped muscle cars rely on mechanical gauges to validate system performance during tuning and road testing. The gauge's standalone operation makes it particularly valuable in vehicles with custom wiring or non-standard ECU configurations where sensor integration becomes problematic.

AutoMeter gauges are recognized for accuracy and durability in high-heat engine bays. The Cobalt line represents the manufacturer's mid-range offerings, balancing cost-effectiveness with reliable performance for street and performance builds. Proper installation includes isolating the pressure line with a snubber valve to protect the needle from oil surge and pressure spikes common in dynamic driving conditions.
