xTAUTOY Oxygen Sensor Kit for Subaru: Upstream and Downstream Precision
Upgrade your Subaru with the TAUTOY 2-piece oxygen sensor kit, designed for 2.0L and 2.5L engines across multiple models. This pair consists of upstream 350-34052 and downstream 350-64031 sensors, sourced to align with OEM part numbers and fitment expectations. Built to deliver accurate readings of exhaust gases, these sensors help you monitor the air-fuel balance as you drive, potentially contributing to steadier idle and smoother operation in day-to-day conditions.
Manufactured with a double laser-welded stainless steel body, the sensors are engineered for durability and consistent performance. The robust construction can endure temperature variations and road conditions, supporting long-term reliability in your daily commute or weekend trips. While individual results can vary, many drivers notice a more responsive feel as the engine control system calibrates the fuel mix more precisely over time.
What’s Included and Where It Fits
- 2 sensors total: upstream 350-34052 and downstream 350-64031

The sensors are designed to measure oxygen partial pressure with accuracy, enabling more informed control of the air-fuel ratio. This can translate into a more efficient combustion process under various driving scenarios, from city errands to highway cruising.
