RACOONA Oxygen Sensor Upstream & Downstream — Compatible with E150/E250/E350, F-Series

RACOONA Oxygen Sensor: Durable, precise replacement for your engine

Reliable oxygen sensing is a cornerstone of smooth, efficient engine operation. The RACOONA Oxygen Sensor is engineered to deliver stable, accurate data to your vehicle’s engine management system, helping the ECU fine‑tune the air‑fuel mix for responsive starts, steady idling, and steady drives. Its design combines rugged materials with precise manufacturing, so the sensor can withstand the heat and vibration of everyday driving while maintaining consistent performance over time. A double laser welded stainless steel body provides a sealed, long‑lasting core, and the fully submersible construction helps protect against harsh engine environments.

Why this sensor stands out

• Durable build: The double laser welded stainless steel body is designed for longevity and reliable operation in demanding conditions.
• Sealed, long life: Fully submersible sealing supports enduring performance, resisting wear from road conditions and heat.
• Accurate data transmission: Engineered to deliver clean, precise data to the ECU for optimal engine operation and potential longevity benefits.
• Air-fuel ratio sensing: Precisely detects the mixture of air and fuel, helping the engine respond to changes in driving conditions.

What’s included in the package

• 1 upstream oxygen sensor
• 1 downstream oxygen sensor

Replacement identifiers include 15716, 15717, 15718, 15719, ZZC318861, XR3Z9G444CA, 15664, 234-4401, and 234-4046. The sensors are designed to fit a range of popular models and configurations, offering a practical upgrade path for your vehicle’s emissions and performance monitoring system.

Compatibility and installation notes

• Designed for models such as E150, E250, and E350, as well as F150 and F250/F350 ranges from specified years. Always confirm the original sensor is the same type and that the plug matches the vehicle harness before purchase.
• Plug compatibility matters: if the plug differs from the original component, this sensor may not fit your vehicle. Compare the original sensor on your car with the product image to ensure a correct match.

Real‑world use possibilities

If you’re maintaining an older fleet or upgrading maintenance parts, this RACOONA sensor offers a practical, replacement option that emphasizes durability and precise data. While results can vary by vehicle and driving style, users may notice steadier idle, smoother throttle response, and a well‑managed air‑fuel ratio when paired with a compatible ECU setup.
