Issue * came across harvesting a MAf today
The MAf on NA cars are made by DENSO and mount with two M6 (10mm head ) bolts
The bolts are typical steel but bolt into brass threads fused into the air cleaner
I had bad galvanic corrosion on one of mine, so bad the fused and broke the threaded insert ou to the plastic
I had to Dremel it put and re-epoxy the insert into the MAF
Check your cat too, while you test your bolts.
P80 NA DENSO MAF mount bolts issue 1275636

Your cats appear to be bad, both are missing their precious metals =P
Wisdom requires knowledge as a prerequisite, but knowledge can be developed due to a lack of wisdom.
In order to learn how to fix something, you must first learn how to break it.

The cats also look dark - may need cleaning. Might be too rich condition.

Clarifying a bit more
The design is m6 bolt, clearance. Brass boss on air cleaner housing, threaded brass m6 insert in MAF, two pieces.
Look how the bolt corroded in the brass boss, but not in the insert.
Strange. When I went to unscrew this it locked up in both, then broke the insert out of the MAF. It was also locked into the brass boss.
