Bosch 2" Mechanical Vacuum & Boost Gauge — Black Dial and Bezel, 0–20 PSI, 270° Sweep

The Bosch SP0F000050 is a 2-inch mechanical vacuum and boost gauge with a black dial and bezel, delivering precise 0–30 in. Hg vacuum and 0–20 PSI boost readings with a wide 270° sweep.

Compact, accurate and built to fit standard 2-1/16" openings, this Bosch Style Line gauge blends racing-derived accuracy with automotive-friendly styling. It combines Bosch engineering with a clear, high-contrast display and built-in lighting so you can monitor intake vacuum and boost levels day or night. The package includes tubing, fittings and mounting hardware so it’s ready for installation in custom dashboards, instrument pods or replacement panels.

How does this gauge measure vacuum and boost?

The gauge uses a mechanical movement calibrated to show vacuum from 0 to 30 in. Hg and boost from 0 to 20 PSI across a 270° sweep. That broad sweep makes the pointer easy to read at a glance and provides finer resolution for small pressure changes.

• 0–30 in. Hg vacuum range for intake monitoring
• 0–20 PSI boost range for turbo/supercharged systems
• 270° pointer sweep for improved visibility

What are the size and installation details I should know?

This is a standard 2" (2-1/16" panel opening) instrument designed to drop into common gauge pods and dash cutouts. Bosch supplies a removable black mounting panel, mounting hardware, 72" tubing and fittings to simplify setup; electrical hookup is a single 12-volt illumination feed.

• Standard 2" black dial fits 2-1/16" openings
• Black bezel with removable mounting panel for neat installs
• Includes 72" tubing, fittings and mounting hardware
• 12V internal backlighting for night visibility

How readable and durable is the display?

The Style Line design emphasizes a sharp contrast between the pointer and dial so you can see readings quickly while driving. The black dial with bright pointer and internal lighting provide clear visibility; Bosch-built mechanical internals are engineered for long-term stable readings under normal automotive conditions.

• High-contrast pointer and dial for quick reading
• Internal 12V illumination keeps the face visible after dark
• Durable bezel and mount for routine automotive environments

Who is this for? The Bosch SP0F000050 is ideal for drivers, tuners and mechanics who want a compact, reliable vacuum/boost indicator for daily-driven or performance vehicles. It works well as a factory-style replacement in custom pods, as part of a track package where monitoring intake pressures matters, or for anyone upgrading dash instrumentation with a precise, easy-to-read gauge from a trusted automotive brand.
