The look competely different. The SOHC maf looks really funky.

It could be used if you have a way to tune for the signal...

The S13 DOHC and SOHC look very similar, but the DOHC is only three pins, SOHC and SR are four pins.

I happen to have all three right here!
SOHC 3pin 3whole plug 40F00
DOHC 4pin 4whole plug 53F00
SRs13 3pin 4whole plug 52F00
SR and SOHC are Hitachi, DOHC says nissan on top jecs on lable
SOHC and Sr look identical minus element plug
my 93 DOHC housing looks similar but the element looks different and the pins angle 90deg

Yes, SOHC mafs works on an s13SR.
