What air filter you running?

I killed one afm with stock filter. Then I killed one will an aftermarket dry filter. Think its maybe a blitz filter Checked the plug Earths look to be ok. There must be a problem. Because its happening to a lot of others.

How often are they dying?

Did one then another died 6 months later One dies with stock filter. Second died with dry panel filter think its a blitz one

There is another car that is doing this- its Rudis car. In my opinion its either getting too dirty, and dying, or there is an electrical gremlin in there shorting it or applying too much load. It is possible that the AFM circuit in the ECU is fried, has happened to cars on the O2 sensor circuits in the ECU- but I don't know how you go about testing diagnosing that, and I would think it would effect drive-ability which you'd notice.

When I tested Rudis car, the AFM read normally, wasn't spiking or anything and the ECU had not logged any CELs.

If it was my car- I would get a new nissan panel filter, clean my airbox out to be spotless (front/back/underside etc etc), and get a can of MAF/AFM cleaner, and give the wire a squirt every couple of months to clean it. Then see what it does.

When I pulled the new nissanafm out it was spotless. The box was cleaned about 4 months ago . No fault codes Weird one.

Looks clean and is clean are two different things. Anyway, then the only thing I could think of would be to trace the wire back and inspect the condition of it up until the loom (it would get difficult but not impossible once you get to the loom...). Disconnect battery, get your ECU out and have a real good look at all the joints you can to see, and see if one is dry or shows signs of overload / water damage etc

No other ideas, sorry.
