Description
Product Overview
The XOPIYAO Exhaust Gas Temperature Gauge is engineered to give drivers real‑time insight into exhaust gas temperatures, a critical parameter for engine health and performance. Constructed from premium die‑cast aluminum and reinforced polymer, the gauge offers durability against vibration and heat. It features a precision‑calibrated temperature sensor that plugs directly into the exhaust manifold, delivering accurate readings from 0°C to 1200°C. The analog display uses a bright red needle and offers seven selectable color backdrops—Blue, Red, Green, Teal, Purple, White, and Yellow—optimizing visibility for day, night, and low‑light conditions. Dimensions are compact at 6.77 x 4.88 x 3.11 inches, and the unit weighs just 9.9 ounces, making it suitable for a wide range of vehicle dashboards and gauge clusters.
Usage
Designed for both daily commuters and performance enthusiasts, this gauge excels in monitoring exhaust temperatures during city driving, long‑haul trucking, and track days. Install the sensor on the exhaust pipe before the catalytic converter to capture true gas temperature, then route the wiring to the gauge mounted on the dash. The clear red needle and customizable background colors help drivers quickly assess engine load, prevent overheating, and fine‑tune fuel mixtures. Ideal for diesel trucks, gasoline performance cars, and off‑road vehicles where temperature management is essential.
