What are the dimensions of the cone air filters you are using? The K&N one I have I made a mistake with the dimensions, so instead of being able to be clamped on the outside of my AFM setup, it actually slides right in. While this doesn't bother me, when I go to change my intake setup I'd like a cone filter, however, I'm not sure how exactly to go about with the dimensions. K&N's website makes it a tad confusing. So, I was hoping someone can just give me a cheat sheet.

A part number will work just as well.

 

Im not sure how you are trying to mount a cone filter over your AFM because you need an adaptor to bolt onto the AFM first. Then whatever outside diameter the adapter is will determine the ID of the filter used.

The setup that I just sold used a 3 inch OD adapter for the filter to go over.

 

I just didn't word it corretly. I'll provide a picture to what I'm talking about. I no longer have the red air filter (it was an eBay special that came with the Miata adapter) and looking for something that'll fit on there and not be as huge as that thing. I've seen them on a few other cars, but wasn't sure what those dimensions were.

I am looking at ReSpeed's radiator support that has that hole in the side for a tube to go through it. This is why I ask.
