Hi guys!!! I am in desperate need of replacing some sensors in order to pass smog test. Does anyone know any dealer that sells Maxima sensors such as Denso or NTK? I prefer Japanese sensors as they are meant for the car. Any number, link or something? Thanks.

 

Rockauto is likely your best bet. Search for coupon codes as there's usually one for 5% off your order.

 

It's a smart move sticking with Japanese brands.

Just google Hitachi, Denso etc... along with the part, year and Maxima. This searches nearly all the sellers and lists them by price if you want.

There are tons of sellers out there and I'm not loyal to any of them. A lot of the time Amazon has the best price but not always.

 

Depends on the codes. You may replace the O2 sensors and still have the same code(s).

 

Who makes the OE O2 sensors for our cars anyway? I've read Bosch in some places, Hitachi & Denso in others. For my Hondas, it's all Denso.

 

Yeah. Likely bad cats.

Primary or secondary O2, OP?

 

Bosch is OE on 5.5 gen. Don't know about 5 gen. I replaced mine with Bosch and its the exact same as the one that came out of the car.

 

Bosch on the 5gen as well
