I don't have instructions, but I did mine a couple months ago and it took less than 5 minutes without any instructions. I believe I took off part of the engine cover which required removal of a few pins. Then the air box was right there and there were like 3 or 4 clips to undo it. Just try it.
I appreciate your input...you're right, it wasn't very difficult at all. Hopefully there will be other things I can do that won't be too difficult either. I like doing things myself when I can...nothing major: oil changes, filter changes, etc.
