It happens!
Changed to LS7 airbox on my '09 a long time ago.
More intake sound and ugly Helmholtz resonator gone. Like it much better.

Cool, thought it did. Just couldn't recall for sure. Looking forward to cleaning up that area with less housing.

Fits like a charm.

However unlike most when I did it to my LS3 it developed a slight lean stumble, and the A6 didnt shift properly.

Did some data logging and the LS7 intake without the resonator did show MAF changes and it affected the tune which is tied together with the A6.

Were you able to identify and tune it out or change it back?
