O2 Oxygen Sensor Downstream for Nissan Frontier Xterra, Suzuki Equator 234-4313

Upgrade your Nissan Frontier, Xterra, or Suzuki Equator with this downstream O2 oxygen sensor (Part 234-4313). Designed to monitor exhaust gas after the catalytic converter, it helps regulate the air–fuel ratio for efficient combustion, lower emissions, and smoother performance. Replacing a worn downstream sensor can reduce rough idle, improve throttle response, and help your vehicle pass emissions tests with confidence.

Compatibility highlights include Nissan Frontier 2005–2012 (4.0L) downstream right; Nissan NV series (NV1500, NV2500, NV3500) 2012–2019 (4.0L) downstream right; Nissan Pathfinder and Xterra 2005–2012 (4.0L) downstream right; and Suzuki Equator 2009–2012 (4.0L) downstream. The part carries OEM references such as 234-4313 and aligns with multiple OEM codes like 226A0-EA210 and 18213-82Z30 to ensure a precise fit. This sensor is piezoelectric and features heating, delivering fast response times and reliable readings across temperature ranges.

This aftermarket sensor is a direct-fit replacement designed to meet or exceed OEM specifications. It’s engineered to integrate with your vehicle’s ECU to deliver accurate oxygen readings, supporting optimal fuel economy and cleaner exhaust. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
