Hi Bob & List,

This is a commercially available product.  I investigated
making one for my previous vehicle but decided it was not
worth the trouble.  The universal adaptors are from Split
Second:

but they cost a mint.  There are a number of companies that
will custom make them as well, also for a fair chunk of
change.

If you are really keen on removing restrictions and have a
bit of time on your hands, the other option is to remove
the MAF entirely:

or

I'm EXTREMELY curious to hear the results of the dyno
testing!  Please do keep us informed.

All the best,
