2-1/16in Z/S Boost Gauge - 0-100psi

The AutoMeter 2-1/16in Z/S Boost Gauge - 0-100psi is an essential instrument cluster addition for any turbocharged or supercharged vehicle owner serious about monitoring engine health and performance. This mechanical boost pressure gauge provides real-time feedback on intake manifold pressure, enabling you to verify proper turbo or supercharger operation and catch dangerous over-boost conditions before they damage your engine.

Whether you're tuning a street performance build or diagnosing boost system issues, accurate boost pressure measurement is non-negotiable for reliable power delivery and component longevity. AutoMeter's Z/S series combines precision analog measurement with a refined gauge design that fits seamlessly into modern dash configurations. The 2-1/16-inch diameter housing accommodates the robust internal Bourdon tube mechanism, which converts boost pressure directly into needle deflection across a 0-100 psi range—sufficient for mild to moderately aggressive turbo applications.

The Z/S line features AutoMeter's signature bright, easy-to-read dial markings and a durable construction that withstands vibration, thermal cycling, and the inherent pressure spikes of forced-induction systems. Installation is straightforward: a simple 1/8-inch NPT sensing line connects directly to a boost tap on your intake manifold, requiring no external power or complex wiring. Turbocharged and supercharged enthusiasts benefit most from this gauge when upgrading to custom ECU tunes.
