Eek. I don't know about that sensor. They're sensitive to having the right one and I can't guarantee that's it; I don't know about Denso or the HX, but I know some Chryslers won't run correctly on an aftermarket O2 sensor...NGK made them for some Chryslers, but the OEM and aftermarket businesses were different entities (NTK was NGK's OEM division), and you wanted the NTK sensor made by NGK's OEM side from a Chrysler dealer, not the supposedly correct NGK from a parts store. Given that lean burn relies heavily on inputs, your skepticism is warranted...
