02 Sensors!

[ZSHO]

I had my Front wide-band sensors replaced a few months ago and here are the part numbers for anyone interested.
These are the part numbers for the 13+SHO .

I found http://www.rockauto.com to have the best price.
If you see an error please LMK,thanks.  Z

The Front 02 sensors are both wide-band IIRC and require two sensors using the same part numbers. .
There is a TOTAL of five 02 sensors required on the vehicle...

Sorry for the delayed response.......I noticed much more power to the wheels. 
The front wide-band 02 sensors are crucial for optimum performance and even when faulty they do not emit codes easily IMO.  Z
