So I had to see what I can do to improve on what I am reading in this thread. Again, if I had know that some of you were having some issues, I would have done this a while back. This is what I came up with, as it sounds like the heat coming from the flanges is an issue.
With the previous version of the heat shield I was concerned about shielding the filter screen itself, so the shield sat further forward. With the revision, the flange is also taken into consideration:
The lower flange bolt will need to be longer, instead of 1.5" it would need to be 2", so that the secondary nut can in installed (which holds the heat shield), after the flange bolt has been tightened.
