Not a stupid question at all.  Nothing special about the sensor but note that it is a variable reluctance sensor, not Hall effect.  Most any VR type will work but some are more reliable than others.  The Subaru does not have a good track record based on the number of Soob flyers who have had failures and asked me to make dual pickup versions for the EJ-2x & EG-33 engines.  I have not heard of a Mazda sensor failing but that is of course no guarantee that it can't happen. 
 
Do be sure to check the polarity of any VR sensor used.  The output should swing positive as the tooth moves toward it and negative as it moves away.
 
Spent yesterday configuring my oil system on the RV-8.  I should have heeded Rusty's warning on those "Easy push-on oil line fittings"  The Summit description says "no more busted knuckles trying to assemble oil lines".  Ha!  I'm an FAA "standard 170 lb pilot" but that is not enough force to put on those blasted fittings.  Anyone know a trick to make them easier to put on?

Tracy, I don't really expect you to know such trivia, but it can't hurt
to ask.  The eBay  store with the RX-8 crankshaft sensor has a bunch of
other models, so for as little as $5.  Is there anything special about
this particular model, or is it just a hall effect sensor?  Some of the
other model numbers looked like they had long mounting arms that would
make installation in an RX-7 series a tad easier.
