There will be quite a few differences in installing an Injen, as you're replacing the entire stock air intake plenum (accordion tube) with a straight-pipe. Also, the Injen MAF adapter doesn't bolt to a mounting bracket, nor does the Injen's MAF adapter have threads in it, so you have to put a nut on the other end, etc. I guess the only thing you can really use from the Mirko Racing Intake install How-To for an Injen is the pulling of the IAT, and the bolt sizes/socket sizes that you'll need. :shrug:
