The Light Is Gone

The Denso brand comes with a favorable reputation and rightfully so. The impression I felt when I opened the box was that these O2 Sensors were quality made. Now that they have been on my vehicle for several months I can say that I am very pleased with my purchase.

Great performance for the money

Always good luck with Denso O2 sensors in GM trucks. Much more reliable than Bosch and half the price.
