It does not come with instructions but install is very simple. Maybe a half hour if you take your time. Once you remove the stock ic, everything makes perfect sense. If you're concerned I could put something together for you to help guide you through the install.
This also a good time to install an aftermarket BPV (if you haven't yet). Shameless plug, but I'm also selling my Forge BPV in the main classifieds section
