AutoMeter 5704 Phantom 2-1/16in Mechanical Boost Pressure Gauge 0-35 PSI White

Vehicle Fitment

• Universal - fits any street or race vehicle equipped with a 1/8" NPT boost pressure port
• Compatible with all gasoline, diesel, and forced-induction engine types; no vehicle-specific fitment restrictions

Fitment Notes

• Mechanical gauge - requires a direct 1/8" NPT boost pressure line connection from the intake manifold; no wiring or sending unit needed
• Gauge opening diameter is 2-1/16 in. (52mm); verify pod or panel cutout matches before installation
• Route the nylon pressure line through the firewall; use a snubber or restrictor fitting to dampen needle vibration at high boost levels
• Optional braided stainless boost line kits (e.g., AutoMeter 3223) are available separately for cleaner installations

Features

• Bourdon tube mechanical movement - delivers precise, real-time boost pressure readings with no electrical system required
• Full-sweep 270° dial for maximum resolution across the 0-35 PSI boost range
• Fluorescent orange pointer for quick, at-a-glance monitoring under all lighting conditions
• White incandescent perimeter lighting for clear nighttime visibility
• White dial face with black numerals and black powder-coated bezel - the distinctive Phantom series aesthetic
• Bronze bourdon tube and durable nylon gearing for long-lasting accuracy in harsh environments
• Simple 1/8" NPT connection - all required hardware and nylon line included
• Made in the USA; backed by a 1-year limited warranty

Product Description

The AutoMeter 5704 is a Phantom series mechanical boost gauge monitoring 0-35 PSI in a 2-1/16" (52mm) housing. Featuring a bronze Bourdon tube movement with a full 270° sweep, it delivers precise boost pressure readings without requiring any electrical connections - compatible with every street and race vehicle regardless of electrical system. The white dial face, black numerals, fluorescent orange pointer, and black powder-coated bezel give the 5704 the signature high-contrast Phantom look trusted by racers and custom builders worldwide.

Installation is straightforward - a 1/8" NPT connection from the intake manifold feeds the included nylon pressure line directly to the gauge. A 1/4" NPT adapter is also included for larger pressure ports. Suitable for all forced-induction applications including turbochargers and superchargers on gasoline and diesel engines. For builds requiring a cleaner line installation, the optional AutoMeter 3223 Boost Line Kit is available separately.
