Searching many many many forums and Volvo parts sites for a new front and rear oxygen sensor for my '99 S70 2.5L standard sedan.
I see there a few different sensors labelled as belonging to this model, but I know this is impossible as there are only 2 to be replaced.

Can someone please clue me in as to which ones I should order??

Thanks.

You can try a Bosch, some are OK, but some cars just do not like aftermarket 02 sensors

 

Hey.
I realize that I should get the OE sensors if possible,
But i'm seeing too many on the parts websites that seem too similar.

Forgive my newbie-ness....


But what is the difference between:

* Bosch Front Oxygen Sensor - Direct OE Replacement
1999 Volvo S70
Bosch Oxygen Sensor

The Bosch oxygen sensor utilizes a mix of zirconium and yttrium oxides and other elements to form a tough base that withstands the intense stress to which oxygen sensors are subjected. Each element is incredibly strong for best-in-class performance and maximum service life.
OE-Equivalent.
Direct fit for easy installation.
OE Style connectors and wire lengths.
Base ceramic probe of Zirconium and Yttrium.
Patented Platinum Power Grid.
Fine particle filter.
From overall sensor design to the critical ceramic element, Bosch is known worldwide for quality and performance.

Installation Notes: Vehicles equipped with Air Fuel Ratio Sensors may look very similar to the Oxygen Sensor. Please confirm the correct part before ordering and if the connector does not match, do not install.

Warranty Information: 12 month - 12,000 mile limited warranty against defects in material and workmanship.

AND WHY IS THE NON-OE PART ALMOST $150 more.

 

Is there anything else I should look for when purchasing??

Thanks.

 

I can't answer that but it's a 50/50 when you don't buy the Volvo blue box sensors.
However, a good many times the Bosch works just fine, give it a shot
