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.

OSA60238
The sensors were is to install and my vehicle is running great since the installation of the sensors . Once again alone Auto has provided me great parts and service.
The Cadillac converter sensor was pretty much really good. Helped my car a lot good and mileage so I will recommend people using this website. They send me my stuff really fast and customer service is five stars.
Perfect fit
Even though the part was said to have fit my 2007 Cadillac Dts, the O2 sensor would not clear when inspection was due. Put an additional 120 miles on in hopes the code would clear and it did not. Had to bring car in for servicing and was told my mechanic, the O2 sensor was bad. He replaced it with a Delco O2 sensor and my inspection was cleared.
