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.

Great product
One sensor was defective?.Slow getting replacement?..Was supposed to receive on March 13 ?.Had to make a 2nd request?..Finally received on March 20?.. Had to pay COD fee?.. Had been previously impressed with 1A service?..Not this time?
I bought these 4 oxygen sensors for my 2005 toyota tacoma V6 about 6 months ago. 2 upstream sensors failed one after another. I tested them with the multimeter for Ohm and voltage. All are out of range, means they all failed after 6 months.
The customer experience was great and the parts came in a timely manner and they were plug and play parts, the figment was perfect
1A Auto's customer service exceeded my expectations. I bought an O2 sensor kit for my 2007 FJ Cruiser, but the sensor connector didn't match. They refunded my purchase promptly, and I'm grateful for their efficient service.
Installed them, took it to a dealership and they were doa
Worked great, came with antisieze on the threads, easy fit, connectors and wire were a little longer than stock, just had to make sure they didn't lay on the exhaust pipes.
Sensors working well, will see with time but please with the results .
great value
Highly recommended, quality and service 100%.
Thank you for your inquiry! Could you please provide us with your 17-digit VIN?
