Is your check engine light on for an O2 sensor? This A-Premium replacement is a direct fit for several Nissan and Infiniti models. It’s a downstream heated sensor (that means it’s after the catalytic converter) with a 4-wire connector and threaded mount. The part number matches OEM 250-241104, so you know it’ll plug right in. Compatibility includes: Nissan Versa 2012-2019 (1.6L), Versa Note 2014-2017 (1.6L), and Infiniti M35h 2012-2013 (3.5L), Q50 2014-2018 (3.5L), Q70 2014-2018 (3.5L). The sensor is about 375mm long overall, with a female connector – just unplug the old one, unscrew it, and screw this one in. No special tools needed, just an O2 sensor socket or wrench. It’s built from quality materials to last and comes with a one-year unlimited-mileage warranty for peace of mind. A-Premium is known for reliable aftermarket parts, and this sensor helps restore proper fuel trim and emissions performance. If you’re getting codes like P0137 or P0157, or just notice poor fuel economy, a fresh O2 sensor can make a difference. Easy install, good price, and it gets your car running right again.
