2-1/16in Ultra Light Oil Temp. Gauge

The AutoMeter 2-1/16in Ultra Light Oil Temperature Gauge (part number 4347) is a lightweight electric analog instrument designed for precision engine monitoring in high-performance and competition applications. This ultra-lite gauge delivers reliable oil temperature data across a 100–250°F range, enabling drivers and technicians to maintain optimal engine operating conditions during sustained track use, towing, or demanding off-road operation.

The 2-1/16-inch diameter with short sweep needle architecture fits standard gauge clusters and aftermarket dash panels without requiring extensive modification. AutoMeter's silver face provides clear contrast and readability under variable lighting conditions—critical when drivers need instantaneous feedback on fluid state. The electric sensing system responds quickly to temperature changes, delivering responsive needle action that reflects real-time oil conditions rather than lag-prone mechanical designs. At 0.65 lbs, the ultra-lite construction minimizes unsprung weight and simplifies installation in confined engine bays where traditional gauges consume valuable space.

This gauge suits hot rod builders, motorsport enthusiasts, and operators running modified or turbocharged engines where standard factory instrumentation lacks precision or range. Oil temperature data helps prevent bearing damage from cold starts, identifies cooling system failures before catastrophic overheating, and validates engine tuning adjustments. The AutoMeter oil temperature gauge integrates with existing wiring harnesses and sensor-type transmitters, making it a direct upgrade path for vehicles requiring aftermarket instrumentation or replacement of failed factory gauges.
