If your getting a wideband im gonna asume your going to get it tuned, have the guy tune the cel off. like have him turn off the rear o2 you should pass inspection since there is an o2 sensor and such.

Just buy the aem for like 175$ on ebay and its a plug and play like it was stated above.

I got an auto meter air/fuel and it costed me 150$ brand new off craiglist
