The AutoMeter 2-1/16" Cobalt Boost/Vacuum Gauge (Part Number 6103) is a mechanical analog instrument designed to monitor both positive boost pressure and negative vacuum in automotive fuel systems, induction systems, and diagnostic applications. With a dual-range scale reading from 30 inches of mercury on the vacuum side to 30 psi on the boost side, this gauge delivers real-time pressure data essential for engine tuning, supercharger diagnostics, and turbocharger monitoring on high-performance vehicles and boost-equipped engines.
The 2-1/16-inch diameter face with black background and cobalt blue accents offers high visibility in both daylight and dimly lit engine bays. The mechanical needle response provides direct, lag-free readings without electronic dependency, making it reliable in harsh underhood environments where temperature swings and electrical noise are common. The sealed analog design requires no batteries or signal processors—only a straightforward hose connection to the measurement point—ensuring durability and simplicity in installation and long-term operation across diverse automotive platforms and climates.
This gauge serves engine builders, performance tuners, and diagnostic technicians who need accurate boost and vacuum measurement for carburetor jetting verification, fuel pressure regulation, manifold vacuum assessment, and boost pressure validation on forced-induction engines. The dual-range capability eliminates the need for two separate instruments, streamlining dashboard or test panel integration. Its compact footprint and standard mounting provisions allow flexible installation in custom gauge clusters, portable diagnostic kits, or mobile performance measurement systems.
AutoMeter's analog gauge line has established itself as the standard in performance automotive measurement, valued for accuracy and mechanical reliability in conditions where precision and responsiveness matter. The 2-1/16" Cobalt Boost/Vacuum Gauge combines proven mechanical design with a professional appearance, making it a trusted choice for both street performance and serious engine development work.
