2-1/16 U/L Boost Gauge 0-15psi

The AutoMeter 2-1/16 Ultra-Lite Boost Gauge 0-15psi (model 4302) is a mechanical, analog pressure monitoring instrument designed for turbocharged and supercharged engine applications. This compact gauge delivers real-time boost pressure feedback with direct mechanical linkage, eliminating electronic lag and offering straightforward reliability in high-vibration environments. The 2-1/16-inch diameter housing with silver face provides clear visibility across varied lighting conditions typical of engine bay and cockpit environments.

The 0-15 psi measurement range covers light to moderate boost levels, making this gauge suitable for street and mild performance applications. AutoMeter's mechanical design eliminates power source dependency—a critical factor for reliability during extended off-road use, high-altitude operations, or scenarios where instrument cluster redundancy matters. The Ultra-Lite construction reduces overall dashboard or pod weight while maintaining the accuracy and durability expected from analog pressure instruments. At 0.6 lbs with compact dimensions (4.85 x 4.5 x 5.05 inches), this gauge integrates easily into existing instrumentation layouts without requiring significant structural modification.

This boost gauge serves operators and enthusiasts running boosted powerplants who need direct, unfiltered pressure telemetry without digital complexity. Recovery vehicle operators, off-road competitors, and engine builders value mechanical gauges for their transparent operation and field-serviceable construction. The 0-15 psi range is well-suited to naturally aspirated engines running mild supercharger or turbo kits, as well as experimental aerospace and marine applications requiring simple, robust boost monitoring.

Mechanical analog gauges remain a cornerstone of specialized vehicle instrumentation, particularly where electrical noise immunity and fail-safe operation are priorities. AutoMeter's track record in motorsports and off-road markets has established the brand as a standard supplier to professionals who demand precision without proprietary software dependencies.
