Can some post a pic of their AFM Air filter adapter?
 

I think i might have the wrong one on my 87 TII. It bolts right up to the Air Flow Meter, but the hole is sorta small and square...not really sure if its the right one. Can someone post a picture or a link to the RIGHT ONE FOR A 87 RX7? Thanks.

Here's the HKS one, sold by k2rd.. It's like 20$, and works rather well:

yea I have the sme HKS one. The little square opening is all you need. If you look at the AFM you'll see it only has a little square inlet.
