Auto Meter SPORT-COMP II Boost/Vacuum Gauge

Keep a close eye on turbocharger performance with the AutoMeter Sport-Comp II Boost/Vacuum Gauge, designed to monitor intake manifold vacuum and boost pressure in forced-induction applications. Tracking boost levels helps you understand how your turbo system is operating, identify unexpected pressure changes, and keep your engine within its intended operating range. Available in multiple sizes and pressure ranges, these gauges let you match your dashboard layout and boost-monitoring needs, whether you're building a street truck or a performance-focused setup. The mechanical 2-5/8-inch gauges are available with 20 PSI or 45 PSI maximum boost readings, while the 2-1/16-inch mechanical version measures up to 30 PSI. All three mechanical options measure vacuum down to 30 inHg and use a precision Bourdon tube movement for dependable readings, without requiring an electrical connection. Each includes nylon pressure tubing, fittings, a T-fitting, mounting hardware, and white LED through-the-dial lighting. For a smaller electric option, the 2-1/16-inch stepper motor version measures from 30 inHg vacuum to 30 PSI boost and features automatic calibration at startup to compensate for atmospheric conditions. It includes a solid-state MAP sensor and wiring harness for installation. Choose the gauge size, pressure range, and mechanical or electronic operation that best suit your build.
