NTK 21066 Oxygen Sensor Review

Based on my observations, this sensor is an excellent replacement for my automotive needs. The accuracy and durability of this sensor have really impressed me. It was also easy to install and has helped me to improve my vehicles performance .However the only downside I found was that it was a bit pricey compared to other sensors in the market, but I believe that the quality justifies the extra cost. Overall, I am satisfied with my purchase and would recommend it to anyone looking for a reliable

Perfect replacement for my Silverado. This is a replacement for the downstream (post catalyst) O2 sensor. The check engine light went out immediately after installation. It's easy to replace, but I'd recommend buying a special nozzle ($10 here at Revain) to loosen the old one and squirt it with a liquid wrench before attempting to remove it. It was also a lot cheaper than the national parts store for the exact same product.
