Title: 6v and 8v air cleaner differences question
Post by: Hotrodjohn71 on February 11, 2026, 10:49:23 PM

Is there a difference in the oval Ford air cleaner top plate between the 6v and 8v air cleaners?

Is there a difference in the holes spacing?

How can I tell whats what?

Thanks,
John

The only difference I have found is the hold down holes are not in the same location.

I can't speak to the 2x4, but on my 3x2 air cleaner, the hold down holes are 10" apart.  Also, the air cleaner is shifted to the front:  From the back hole to the back (firewall) end of the air cleaner is 6 1/4".  From the front hole to the front of the air cleaner is 5 1/4".  Figure if someone has an unidentified lid, this may help determine what it fits.
