AutoMeter - 2-1/16" Boost Gauge 0-35 PSI Mechanical - 4304

This mechanical boost gauge from AutoMeter is designed for monitoring positive pressure (boost) up to 35 PSI in turbocharged or supercharged engines. It uses a high-precision Bourdon-tube style meter movement, which requires no electrical signal for the pressure reading — simply a 1/8″ NPT pressure connection.
The face is styled for performance use, and typically includes mounting hardware, nylon line tubing, and compression fittings for installation.
This gauge is ideal for applications where accurate boost monitoring is critical, such as tuned engines, forced induction systems, or performance builds.

Key Features

• 0-35 PSI boost range

• Mechanical operation (no electrical gauge drive required)

• 1/8″ NPT pressure fitting

• Includes tubing and fittings in most kits

Compatibility & Installation Notes

• Mounts in a standard 2-1/16″ (≈ 52 mm) gauge hole — confirm your panel or pod fits that size.

• Requires a clean, secure pressure feed line from the boost source; avoid leaks and kinks.

• Because it is mechanical, ensure tubing routing and mounting avoid excessive vibration or damage.

• Check your boost range: if your engine regularly exceeds 35 PSI, you may need a gauge with a higher range.
