They also fit people building a multi-gauge setup who want air-fuel monitoring alongside boost, temperature, or pressure readings.\u003c\/p\u003e\n\u003ch3\u003eHow to Use \/ Care\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eUse the gauge as a standalone monitoring tool to watch your engine's air-fuel mixture in real time.\u003c\/li\u003e\n\u003cli\u003ePair it with other gauges from the same series, such as a turbo boost, water temp, or oil pressure gauge, for a combined dashboard view.\u003c\/li\u003e\n\u003cli\u003eKeep power connected to the gauge, because the stepper motor needs power to return the pointer to zero.\u003c\/li\u003e\n\u003cli\u003eInstall it in a dashboard pod or panel to see what the engine is doing, as one owner did with this air fuel ratio gauge.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eHow to Choose\u003c\/h3\u003e\n\u003cp\u003eStart with your vehicle's electrical system, since this gauge is built for a 12V DC system. Check that your oxygen sensor is narrowband, because this kit is designed for narrowband sensors only. Confirm you have a 52mm mounting space in a pod, panel, or cup, and buy a gauge cup separately if you do not already have one.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this gauge work with a wideband O2 sensor?\u003c\/strong\u003e\u003cbr\u003eNo. This gauge is designed for narrowband O2 sensors only, and a wideband sensor will not work with this kit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the gauge cup included?\u003c\/strong\u003e\u003cbr\u003eNo, the gauge cup is not included and must be purchased separately. The kit contains the gauge and a narrowband O2 sensor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy doesn't the needle return to zero when the car is off?\u003c\/strong\u003e\u003cbr\u003eThis gauge uses a stepper motor that needs power to return to zero. It is normal for the pointer to stay in place when the power is off.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I install this gauge in a motorcycle?\u003c\/strong\u003e\u003cbr\u003eYes, it fits motorcycles with a 12V electrical system and a 52mm mounting space.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat voltage does this gauge require?\u003c\/strong\u003e\u003cbr\u003eIt runs on a standard 12V DC electrical system, the type found in most cars and trucks.\u003c\/p\u003e","brand":"MyPetiteCar.com","offers":[{"title":"Air Fuel Ratio Gauge \/ Default","offer_id":68292831969479,"sku":"14:200004889#Air Fuel Ratio Gauge;200007763:201336100","price":59.99,"currency_code":"USD","in_stock":true},{"title":"sensor \/ Default","offer_id":68292832002247,"sku":"14:200003699#sensor;200007763:201336100","price":72.99,"currency_code":"USD","in_stock":true},{"title":"Gauge and sensor \/ Default","offer_id":68292832035015,"sku":"14:200004891#Gauge and sensor;200007763:201336100","price":86.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0795\/0332\/7431\/files\/S1c05d798d0df4461963d6535cddf7ac8o.webp?v=1794144877","url":"https:\/\/digitaldashpro.myshopify.com\/products\/52mm-narrowband-air-fuel-ratio-gauge-kit-12v-car-o2-sensor-voltmeter","provider":"Digital dash pro","version":"1.0","type":"link"}
