My guess is that vibration kills the MAF resistors. Thereby the installation should be very flexible: attachement to chassis wia rubber bits, the air tube engine coupling - flexible.
As engine always makes sudden moves & vibrates, all attachement to the outer arc 'takes in all' vibrations causing MAF to vibrate. The 3gen VGE tube's MAF end sits near the center of this arc, and thus is mechanically positioned to near 'neutral' point (from engine movement). It may have longer life span b/c of that. (Otherwise, from airflow point of view, its the worst 'ever' fabricated...)
From this viewpoint, later Maxima engine models's MAF air tube coupling is suspect conduct to engine vibrations to MAF, and thus cannot be too flexible. There exists nowadays marvellous (silicone?) super flexible hosing possibilities in the raw materiel shops.
