If others don't pan out,
I have a MAF sensor for sale. I'm not sure of it's applications and have not used it personally.
There are no tags or numbering. It does says AC Delco. It has 87160 stamped Into the flat portion. It is 3 3/8" hose size in and out. I think this size of inlet and outlet would tie it to a turbo regal?
If someone can vouch for it's heritage, I'd appreciate it.
I will ship it for $75, in USA.
