Appears to be a quality sensor and corrected the problem I was having with the air fuel mixture. It was an exact fit but be aware once you open the sealed sensor, you own it. Sold at a good price compared to local parts store and shipping was relatively fast

Fast Service
On their email it said to keep an eye out that the part should be there by this date. The part actually got to us 3 days earlier then the expected date. I will definitely shop this site for any other parts we may need.
