I have reached a point where I'm too old to make my big body crawl around these Miata's restoring them.  I spent years taking old Miata's and breathing new life into them.  Ended up being a source for the older Miata repairs in my area.  So I accumulated a lot of parts.  I have other Miata parts listings if you are looking for something.  I will be listing over the next few weeks as I sort through all my stashes.  If you are looking for something in particular, I may have it and just haven't listed it yet.  Feel free to ask.

This mass airflow sensor (MAF sensor) is a crucial component for your 1990-1993 Mazda Miata. It is designed to work with the B6S7 13 210A sensor type.

For those of you looking to replace their old or faulty MAF sensor, these are very difficult to get the original equipment parts.  Here's your chance.  This has been in my known good parts and was used to confirm faulty units in the Miatas I repaired. 

The pic with my finger inserted is to show the vane spring is properly functioning and it has full travel.
