Yes, the wheel MUST be a ferrous magnetic material (not magnetized, but
magnetic, I,e, a magnet must stick to the material).

RX-8 sensor is magnetic reluctance. Same type, size & shape as the
3rd gen. In fact if you have a 3rd gen sensor, you can use it if you
can mount it correctly. The Subaru sensors will also work but they are
poor quality (many failures reported) so don't go
there.
Tracy, I hope you know the answer to this question. Does the reluctance
type sensor need a magnetic wheel to work? If the sensor has the magnet and a
coil of wire might the pulse be made by any electrically conductive material?
I am not an EE, rather a ME so I may be showing my "little bit of knowledge"
but if I remember the theory you should just need a conductor to "cut" the
line of magnetic flux. The use of a aluminum tooth wheel wouldn't save much
weight but it would be nice to not have to paint it to prevent rust!
