Yeah, you will def. get your fill on here if you do a search. I haven't done it yet, but when I tear into the plenum I am planning on doing it. There are a lot of mixed reviews on the effects of doing the mod.

Personally I think it will at least decrease the air flow restriction by canceling the redirection of the airflow coming in. But, like I said, I haven't had the chance to do this yet.
