Product Description

The AutoMeter 5903 ES Series boost/vacuum gauge is a rugged, reliable mechanical instrument designed to monitor your engine's intake manifold pressure (vacuum) and forced induction boost in real time. With a dual range of up to 30 in Hg vacuum and 30 PSI boost, this gauge is ideal for turbocharged and supercharged engines as well as naturally aspirated vehicles where vacuum reading is useful for tuning and diagnostics. Featuring a high-precision Bourdon tube movement, it operates without electrical power, relying on a simple 1/8" NPT line connection for accurate pressure feedback.

Finished with a black Super Bezel, crisp black dial, and fluorescent red pointer accented by red LED through-the-dial lighting, the 5903 gauge combines performance-oriented readability with a classic race-inspired appearance. The gauge kit includes all necessary fittings, nylon line, and mounting hardware for straightforward installation into standard 2-1/16" gauge pods, dash panels, or A-pillar mounts. Whether you're tracking boost on a high-performance turbo setup or simply adding a reliable vacuum/boost readout to your daily driver, the AutoMeter 5903 delivers trusted performance and clarity. **Universal fitment for most vehicles that accept 2-1/16" gauges.**
