no matter where you go you'll probably end up getting a rebranded bosch sensor.

Denso is OE for alot of brands and available in the aftermarket.

Just curious, how did you decide the sensors were bad?

Well i just replaced mine because it was a generic one put in by a mechanic. But usualluy if its getting old 35k-60k miles or your gettinn crappy mileage then its time to replace it.

my check engine light was on, and when i retreieve the code it said high voltage to the downstream sensor and the heated part was not working correctly. so i got a new one. put it in and the jeep is running better now than it has in a while so problem solved i guess. thanks guys

replaced mine yesterday, filled up the tank and wheeled today. Great gas mileage! Well, compared to before
