Nice product. Performs great. Easy to install. Just wish it would be available in different colors like black or silver instead of blue.

Dealer cleaned the stock sensor, but codes continued to come and go. I saw in a comment section of one of the Duramax discussions that the problem might be more frequent in EFI treated engines. I therefore purchased this, installed it and 4 weeks later have not had a code show. The engine is a bit peppier.
