AUTO OCCASION Oxygen Sensor 2-Pack - Upstream Air Fuel Ratio Sensor For Nissan/Infiniti Vehicles

Hey Nissan and Infiniti owners, if your check engine light is on or you're getting poor gas mileage, it might be time for new oxygen sensors! This AUTO OCCASION 2-pack includes upstream O2 sensors that work with a ton of models - we're talking Pathfinder, Armada, Frontier, Sentra, Titan, Xterra, Quest, Maxima, Murano, Altima, and various Infiniti models from 2004-2010. These replace part numbers 12499877 and 234-5060, and they're built to match OE standards exactly. The installation is seriously straightforward - the plugs fit right in like they were made for your vehicle (because they were!). Each sensor goes through rigorous testing before shipping, so you know you're getting quality parts that'll give your engine management system the accurate air/fuel ratio readings it needs. Better fuel efficiency, smoother running engine, and no more annoying check engine light - that's what you get with fresh O2 sensors. Just make sure to double-check the compatibility list against your specific year and model before ordering, and you'll be good to go!
