Wobiwina Oxygen O2 Sensor Kit for Ford Focus 2.0L (2012–2018) — 2PCS Upstream & Downstream OE Fit

Wobiwina Oxygen O2 Sensor 2-piece kit replaces OE 2345068 / 2344575 to restore correct air-fuel readings for compatible Ford models.

If your vehicle's ECU is showing O2 sensor faults, low fuel economy, or rough idling traced to oxygen sensors, this Wobiwina two-piece kit provides direct-replacement upstream and downstream sensors engineered to match the original equipment fitment. Each sensor carries the referenced OE part numbers so installation and diagnostics remain straightforward for 2012–2018 Ford Focus 2.0L and certain 2013–2014 Ford Fusion 1.6L models.

How will these sensors affect engine performance and fuel economy?

Oxygen sensors monitor exhaust oxygen content so the engine computer can adjust fuel delivery. Installing a functioning upstream and downstream sensor helps the ECU refine mixture control and catalytic converter monitoring, which can improve drivability and return closer to expected fuel consumption.

• Upstream sensor measures exhaust gases before the catalytic converter for mixture control.
• Downstream sensor monitors converter efficiency downstream of the catalyst.
• Correct signals reduce long-term closed-loop correction and fuel trim errors.
• Direct-replacement fit preserves factory wiring and mounting locations.

Which vehicles and part numbers are these Wobiwina sensors compatible with?

This two-piece Wobiwina kit is designed to fit several Ford vehicles when matched to the listed OE references. Always verify your vehicle’s year, engine size, and OEM part number before purchasing to ensure compatibility.

• Fits: 2012–2018 Ford Focus with 2.0L engine.
• Also compatible with some 2013–2014 Ford Fusion 1.6L applications.
• Replaces OE part numbers: 2345068 and 2344575 (234-5068 / 234-4575).
• Sold as a 2PCS set: upstream and downstream sensors included.

How easy is installation and what should I check before buying?

Installation generally follows the factory sensor locations and uses existing mounting threads and connectors. Basic mechanical skills or a shop with an oxygen-sensor socket will complete the swap; no ECU reprogramming is typically required when the correct OE numbers match.

• Confirm vehicle year, engine displacement, and original sensor part number first.
• Use an anti-seize on threads only if manufacturer instructions permit.
• Disconnect the battery and allow the exhaust to cool before working on sensors.
• Torque to factory spec and verify connector seating to avoid fault codes.

What are the product features and durability considerations?

These Wobiwina sensors are manufactured to meet OE form, fit, and basic function expectations. They are constructed to withstand exhaust conditions, but longevity depends on vehicle condition, fuel quality, and exposure to contaminants.

• OE-replacement design to match factory connectors and thread size.
• Sold as upstream + downstream pair to address both measurement and converter-monitoring roles.
• Durability influenced by engine leaks, oil or coolant ingress, and sensor heating cycles.
• Regular diagnostics recommended if codes return after replacement.

Who is this for: The Wobiwina Oxygen O2 Sensor 2PCS kit is for do-it-yourself motorists and professional technicians needing a direct-fit upstream and downstream replacement for 2012–2018 Ford Focus 2.0L or compatible 2013–2014 Ford Fusion 1.6L vehicles. Choose this kit when OE part numbers 2345068 / 2344575 match your vehicle and you want a straightforward swap to restore accurate exhaust oxygen monitoring and reliable ECU feedback.
