2-5/8in Phantom Boost Gauge 20psi

The 2-5/8in Phantom Boost Gauge 20psi by AutoMeter is an essential instrument cluster upgrade for any serious engine builder or performance enthusiast running forced induction or naturally aspirated applications. This mechanical analog gauge displays boost and vacuum pressure in real time, allowing drivers to monitor turbocharger or supercharger operation with precision. Whether you're tuning a street rod, daily-driven truck, or weekend race car, accurate boost monitoring is critical for detecting boost creep, intake leaks, and optimizing fuel-air mixture under load.

This gauge features a white face with crisp, easy-to-read markings that range from 30 inches of vacuum to 20 psi of boost, covering both negative and positive pressure events. The 2-5/8-inch diameter fits cleanly into most aftermarket pod mounts or dashboard openings without requiring extensive modification. As a fully mechanical gauge, it operates independently of electrical systems—no sender unit or wiring harness needed—making installation straightforward and eliminating potential sensor failures. The robust construction handles vibration and temperature swings common in modified engine bays, delivering reliable readings mile after mile.

Mechanics and tuners favor the Phantom series for its durability and accuracy across a wide range of platforms. Install this gauge on any turbocharged or supercharged engine by routing the line from your intake manifold or boost tap directly to the gauge port; no calibration required. The compact footprint makes it ideal for crowded engine bays or custom dash clusters where space is at a premium. AutoMeter's reputation for precision instrumentation ensures you'll catch boost anomalies before they become expensive problems.
