What Size Filter

I have a cold air intake I got from chrome intakes, and I want to swap the air filter that comes with the intake for a K&N or something higher quality. So my question is, does anyone know what size cone filter I need to get to fit on the intake pipe? Thanks.

It doesnt say anywhere on your intake pipe? it might just be universal fit

Most likely 2.5 or 3. Measure the pipe with a tape measure.
