xinlidatech Oxygen O2 Sensor Kit for Ford F-150 2.7L V6 (2018–2020) — 4pc OE-fit, Prewired

This four-piece xinlidatech oxygen sensor kit replaces the upstream left/right and both downstream O2 sensors for Ford F-150 2.7L V6 Turbocharged models from 2018–2020.

If your F-150 is running the 2.7L EcoBoost V6 from model years 2018, 2019, or 2020, this complete sensor set is built to match the original equipment fitment and wiring length. The kit includes two upstream sensors (left and right) and two downstream sensors, designed to plug directly into the factory harness for most installations. These sensors replace part numbers 234-5174, 234-5173, and 234-8050 and are constructed with durable materials for resistance to heat and road exposure.

How does this kit match my truck's original equipment?

xinlidatech engineered this set to mirror OE-style connectors and harness lengths so each sensor fits without cutting or splicing in typical installations. The sensors use the same mounting thread and electrical interface as the factory parts to simplify replacement.

• Direct-fit connectors for plug-and-play installation
• Correct thread and sensor dimensions to match factory ports
• Replaces OEM numbers 234-5174, 234-5173, 234-8050

What are the materials and durability features?

These O2 sensors combine a stainless steel housing with a ceramic sensing element to withstand high exhaust temperatures and corrosive conditions. They are manufactured under quality checks to provide consistent sensor response and longer in-service life compared with generic alternatives.

• Stainless steel body resists rust and road chemicals
• Ceramic sensing element for quick response to exhaust changes
• Tested to meet industry durability standards

Which vehicles and engine configurations are compatible?

The set is specifically intended for Ford F-150 trucks equipped with the 2.7L V6 Turbocharged (EcoBoost) engine from model years 2018, 2019, and 2020. Confirm your truck’s year and engine displacement before ordering to ensure compatibility.

• Fitment: Ford F-150 Lariat, XL, XLT with 2.7L V6 Turbocharged (2018–2020)
• Verify vehicle VIN or engine spec to match 2.7L EcoBoost
• Includes 1 upstream left, 1 upstream right, 2 downstream sensors

What’s included in the package and how easy is installation?

The package includes four prewired sensors: upstream left (234-5174), upstream right (234-5173), and two downstream sensors (234-8050). Most DIY mechanics can install these with common hand tools and a dedicated oxygen sensor socket; professional installation is an option if you prefer.

• Total: 4 pieces — 2 upstream (left/right) and 2 downstream
• OE-style plugs and harness lengths reduce installation time
• Standard sensor thread fits factory exhaust ports

Who is this kit for? This xinlidatech sensor kit is aimed at Ford F-150 owners and mechanics who need a full oxygen-sensor replacement for the 2.7L EcoBoost V6 (2018–2020). It’s ideal when replacing multiple sensors at once, prepping a vehicle for emissions testing, or restoring accurate air-fuel monitoring after exhaust repairs. Before purchasing, double-check your truck’s year and engine size to ensure proper fitment. If you have any questions about fit or installation, xinlidatech offers after-sales support to help resolve concerns promptly.
