{"product_id":"52mm-air-fuel-ratio-gauge-with-narrowband-o2-sensor-12v-stepper-motor","title":"52mm Air Fuel Ratio Gauge with Narrowband O2 Sensor | 12V Stepper Motor","description":"\u003cp\u003eMonitor your engine's air-fuel mixture with this 52mm air fuel ratio gauge. It works with a narrowband O2 oxygen sensor and fits 12V vehicles that use a stepper motor. The gauge helps you keep an eye on combustion efficiency so you can adjust performance or catch issues early.\u003c\/p\u003e\n\u003cp\u003eThis gauge uses a stepper motor design. It needs to be powered on to return the pointer to zero. If the pointer does not return to zero when the gauge is off, that is normal behavior. The gauge reads from 10 to 20 air fuel ratio, giving you a clear view of your engine's mixture.\u003c\/p\u003e\n\u003cp\u003eThe black plastic housing has a 52mm diameter, which fits standard gauge pods and dash openings. It connects to your vehicle's 12V electrical system. The included narrowband O2 sensor links to the gauge so you get live readings directly from the exhaust.\u003c\/p\u003e\n\u003cp\u003eInstallation requires wiring the sensor and gauge according to the included instructions. The white wires on the sensor are for the heater and do not have polarity. One white wire connects to the battery negative or chassis ground. The other white wire connects to the ACC line of the ignition switch. The black wire on the sensor is the signal line, and the gray wire is the signal ground. The green wire from the gauge connects to the black wire of the sensor. The gray wire connects to the battery negative terminal.\u003c\/p\u003e\n\u003cp\u003eKey Features and Benefits\u003c\/p\u003e\u003cp\u003e- 52mm gauge diameter that fits standard dash openings and gauge pods\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eStepper motor movement provides smooth and accurate pointer response\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eNarrowband O2 sensor included for direct exhaust reading\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eReads air fuel ratio from 10 to 20 for monitoring mixture\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e12V DC operation works with most car and truck electrical systems\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eBlack plastic housing gives a clean racing look to your dashboard\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eWho Is This For\u003c\/p\u003e\u003cp\u003e- Car enthusiasts who want to monitor their engine's air fuel ratio for tuning\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eMechanics and DIY installers adding performance gauges to a vehicle\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eOwners of gasoline-powered cars, trucks, or motorcycles with a 12V system\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eAnyone replacing a broken or inaccurate factory air fuel gauge\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eUsage Scenario\u003c\/p\u003e\u003cp\u003eMark noticed his truck was running rough and using more fuel than usual. He installed this 52mm air fuel ratio gauge in his dash pod and connected it to the narrowband O2 sensor. The gauge showed a lean mixture during acceleration. After adjusting the fuel trim, the gauge returned to a balanced reading. His truck ran smoother and fuel economy improved.\u003c\/p\u003e\n\u003cp\u003eMicro Comparison\u003c\/p\u003e\u003cp\u003eMany basic air fuel gauges use a simple LED bar graph that shows only rich or lean. This gauge uses a stepper motor needle for a more precise analog reading across the full 10 to 20 range. It also includes the narrowband O2 sensor, so you do not need to buy a separate sensor for installation.\u003c\/p\u003e\n\u003cp\u003eSpecifications\u003c\/p\u003e\u003cp\u003eDiameter: 52 mm \/ 2.0 in\u003c\/p\u003e\n\u003cp\u003eMaterial: Plastic shell\u003c\/p\u003e\n\u003cp\u003eVoltage: DC 12V\u003c\/p\u003e\n\u003cp\u003eColor: Black\u003c\/p\u003e\n\u003cp\u003eWeight: 400 g \/ 14.1 oz\u003c\/p\u003e\n\u003cp\u003eInterchange Part Number: boost controller\u003c\/p\u003e\n\u003cp\u003eOEM Number: AFR\u003c\/p\u003e\n\u003cp\u003eOE Reference: 0258006028\u003c\/p\u003e\n\u003cp\u003ePackage Includes\u003c\/p\u003e\u003cp\u003e- 1x Air Fuel Ratio Gauge\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eOR 1x Sensor\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eOR 1x Gauge Cup\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eNote: The gauge cup must be purchased separately.
