Good question. I didn't know there were multiple applications.
I looked at the installation documents on Injen's website. Judging from the vacuum line t' on the one pipe, it looks like my injen intake is a RD1220 that fits the 98 and 99 RS.
And looking at how it was installed on my motor, I don't think it was installed properly. None of those vacuum lines were installed.
Here is the image I am referencing from the RD1220 installation guide.
