A-Premium Downstream O2 Oxygen Sensor for Honda & Acura — Heated 4-Wire, Threaded Direct-Fit

The A-Premium downstream O2 oxygen sensor is a direct-fit, heated 4-wire replacement designed to restore accurate exhaust oxygen readings for compatible Honda and Acura models.

This replacement oxygen sensor from A-Premium is built for downstream (post-catalytic converter) mounting and is offered in configurations that match a wide range of Honda and Acura fitments. It uses a threaded, heated 4-wire design and ships boxed as a single sensor. The unit is intended to match OE connector types and mounting positions so installation is straightforward for technicians and competent DIYers.

Which vehicles will this A-Premium downstream oxygen sensor fit?

This sensor is specified for many Honda and Acura gasoline models across multiple years and engine sizes. Fitment entries include downstream, downstream front, downstream left, and vehicle-specific notes—check your vehicle’s model year, engine code, and exhaust sensor location before purchasing.

• Honda: Civic (2012–2015 L4 1.5L/1.8L), CR-V (2010–2016 L4 2.4L), Accord (2013–2017 L4 2.4L; 2014–2015 L4 2.0L), HR‑V (2016–2022 L4 1.8L), Crosstour (2012–2015 L4 2.4L)
• Acura: ILX (2013–2015 L4 1.5L/2.0L/2.4L), TLX (2015–2020 L4 2.4L)
• Additional downstream front/left fitments include Accord V6, Pilot, Ridgeline, MDX, RDX, TLX V6, RLX, and NSX depending on application

How does the sensor’s specification impact installation and performance?

This sensor features a heated element and four wires, matching the common OE downstream harness for the listed models. The threaded mounting and female connector gender are designed to match factory sockets and simplify replacement, reducing the need for modifications.

• Wire quantity: 4 — heated circuit plus signal and ground for compatibility
• Sensor type: heated — faster warm-up and stable readings
• Mounting: threaded — direct thread-in replacement for factory bung
• Connector: female — matches OEM male harness connectors

Are there part numbers and emissions notes I should check before ordering?

A-Premium lists several cross-reference numbers to help confirm compatibility with your vehicle’s OEM part. Pay special attention if your Accord is a V6 EX‑L/Touring (2013–2017), since the sensor fits both California and federal emissions variants for those models.

• Common reference numbers: 250-24917, 234-4442, 25024917, 2344442
• Additional references: 18050, 24113, 36532REZA01 to assist cross-checking
• Special note: Accord V6 3.5L EX‑L/Touring (2013–2017) compatibility includes CA and federal emissions

Who is this for: This A-Premium downstream oxygen sensor is aimed at vehicle owners, independent mechanics, and repair shops that need an affordable, OE-style replacement for downstream applications on compatible Honda and Acura models. Choose this part when your vehicle’s downstream O2 sensor has failed, thrown diagnostic codes, or when you want a direct-fit, heated 4-wire sensor to match factory specifications. Always verify fitment by comparing your existing sensor’s connector, wire count, and OEM part number before installation.
