I've searched around and haven't seen anyone mention this specific sensor. Anyone tried this Denso? It claims to be wideband and heated, it can be had for under $100, and Denso is a good Japanese brand. Thanks.

 

I think OEM was denso, but not sure if it was that one.

This is the single most important sensor on the car, almost every engine adjustment is based on it.. I would not try to cut dollars here..
