Spek-Pro Oil Pressure Gauge 0-120psi 2-1/16

The Spek-Pro Oil Pressure Gauge 0-120psi 2-1/16 from Autometer is the professional-grade monitoring solution every serious engine builder and performance mechanic relies on. Whether you're tuning a carbureted street engine, diagnosing bearing wear on a tired block, or verifying fresh engine break-in protocols, this gauge delivers the real-time oil pressure feedback that separates guesswork from data-driven tuning. The 0–120 psi range covers everything from vintage muscle cars to modern high-revving builds, making it an essential addition to any diagnostic toolkit or custom dashboard.

Autometer's Spek-Pro series combines precision mechanical movement with a clear, easy-to-read analog face—no electronic complications or sensor lag when you need instant feedback. The 2-1/16 inch diameter (52mm) fits standard 2-inch gauge pods, mounting rings, and custom dash openings without requiring fabrication work. The mechanical bourdon-tube design responds immediately to system pressure changes, allowing you to catch oil starvation or pump failure the instant it begins rather than waiting for a warning light to trigger. Built for vehicles ranging from classic hot rods to modern performance applications, this gauge handles the vibration, heat, and pressure cycling that electronic sensors struggle with over time.

Install the Spek-Pro Oil Pressure Gauge 0-120psi 2-1/16 in any engine running recirculating oiling systems or direct-feed pressure lines—connect it upstream of the filter or to a dedicated take-off port for accurate readings without restriction. Mechanics and engine builders choose this gauge for verification during dyno testing, post-rebuild validation, and continuous monitoring on competition vehicles where oil pressure loss signals component damage before catastrophic failure occurs. The durable construction and straightforward mechanical operation make it equally at home in a street rod engine bay or a shop's diagnostic station.
