My shop just installed the Neo in my Evo 8 and told me I would need an extra Wide range O2 sensor if I wanted it to deliver that info. Cost estimate was $300 like the factory O2 but I see new Bosch 3737 wide range sensors on ebay under $75. Does anyone know the part ID for the right sensor and the straight scoop.

 

If you are trying to get a Wideband o2 you wont find an OEM one...and usually a Wideband is a standalone metering tool such as the LC-1, Zeitronix, Etc.....
