if you have an 86-88 rx7. you need to buy an adapter to go between the air flow meter and filter. HKS has these for about $20. it holds a filter with a 3" hole. hope yours is...
if you have an 89-91 rx7. the filter will bolt right onto the air flow meter. but requires a filter with a 2.5 or 2.75" hole

As scott said, for the s4 you need an adaptor, for the s5's the filter can be bolted right on the air flow sensor.
However, i wanted to add that if you still have an airpump, you'll either need an adaptor with an orifice for the hose for the air pump, or you can get a breather filter for the air pump.
Also, if you don't build a cold air box, or somehow ducting cold air to your intake, you're sort-of counteracting any gain you could get with a higher flowing filter because now you're sucking in hot air which may, under some circumstances cause detonation.

What is the breather filter and what is its purpose?
Also is the thick rubber tubing that connectes to the stock air box the hose that leads to the air pump?

Thanks. So next question is where can I get one and is there a preferred brand that filters better than another?
Also what alternatives are there to getting a breather filter?

Any brand is fine, but here is a link to the K&N crankcase vent filters so you know what to look for.

BTW, here is the adapter needed for the 86-88 AFM:

See one of my later posts in this thread for examples of what to look for.

I have a 91 NA so I will not need the adapter. I do need my air pump for emissions because I live in the land of smog ***** in CA so I will be searching for a breather filter or a crankcase vent filter.
Thanks evil aviator!
