Figured I'd chime in. Just finished installing mine. As everyone said its $130 on amazon shipped. The OP write-up was excellent, a few tweaks of mine; first the "pins" are stainless steel rivets, package comes with 5, I put 2 in each side where the snorkel hood fit over the body, the other 3 I used for the bracket connection to the A-pillar. Rivets are used a lot in sheet metal fab, in conjunction with a rivet tool from Home Depot ($10-$20) you use a 3/16 drill bit and bore it out just slightly and install the mandrel (aka the head end) into the hole and use the rivet tool to mechanically fasten the sheet metal of the A-pillar to the bracket. This provides a much better fastening than using sheet metal screws to connect to the A-pillar.
Another tweak; after all your holes are cut/drilled for the body of the snorkel and ready for install, I installed the rubber "L" shape component on the snorkel so that you can get a nice tight seal with the steel clamp where plastic meets rubber. I then installed the snorkel feeding the rubber in first and through to the airbox area. Once there it took a little heat and application grease on the airbox intake to get the rubber end on the airbox. I had a mechanic friend of mine helping me at that point, as it is easier with an extra set of hands and do not forget to have the hose clamp around the rubber before attempting to install it on the airbox. I did it this way because of easy access to the hose clamps versus after being installed and then trying to get a good seal inside the fender tight against sheet metal. Hope this helps. Below is a drop box link for some pics of what I did, not sure how to upload photos as I'm a NEWBIE.
