Product Features
TRQ oxygen sensors are manufactured to precise specifications using premium raw materials to optimize your vehicle’s emission system. Each sensor is isostatically-pressed for improved strength and durability, and plasma-sprayed to improve sensitivity and prolong the service life of the sensors. Oxygen sensors wear out over time and should be replaced every 60,000 miles to prevent poor engine performance. TRQ recommends replacing the oxygen sensors in sets to optimize fuel economy and reduce overall emissions. All products are fit and road-tested in our Massachusetts R&D facility to ensure we deliver on our promise of Trusted Reliable Quality.

I have always trusted 1a auto. I rely on the dependability and confidence that I will get the right item for the right car also delivery on time Thanks so much
The new sensors have so far solved my check engine light problem and slightly improved gas mileage. As far as which one goes up or downstream is determined by the electrical harness connector.
Ordered o2 sensors, upstream, and downstream Needed to make an educated guest, which was which . Parts worked like they should
Now that I have the right one, it's great.
Just as good as Subaru dealer shipe parts but so much cheaper than dealers prices
great product
Worked perfectly.
The downstream sensor is still throwing a code P0137 the OBDII scanner says voltage below threshold. This indicates the new sensor is faulty.
Perfect fit. Plug and play. The design of the tips were different than OEM, but they are operational and my CE light is no longer illuminating. The savings was amazing as these were a fraction of Subaru OE! We'll see how long they function, but at this price I could replace them 7 or 8 more times before I would spend the money they want for Subaru original parts.
Did not work partial refund issued
