Results of 08 S6 Airbox Modification

[jmswashere]

A couple weeks ago I removed for Restrictor flaps on both of the airboxes on my S6.

I used this as reference: http://m.audiworld.com/showthread.ph...6107&styleid=8

After I did it, there was a very minor increase in acceleration, it revved more freely, and there was a little more noise from the engine.

Today though, I had a CEL thrown for the O2 sensors which I deduce stems from the removal of the flaps and the increase in airflow. I'm going to put the flaps back on and get the CEL reset. The S6 V10 is to finicky to mess with possible fuel/air problems in the future.

If anyone has any suggestions to get around this problem, please let me know. Or if anyone thinks that even with the CEL there won't be any problems down the road.

O2 sensors are at the cats...

Well I guess only one was replaced...so maybe the other bank cat and o2 sensor may have gone out. Guess I will have to see
