It works on the Land Cruiser, but I don't see it working too well on out 3rd Gens. The angle the intake tube runs at is something that you'll have to look into, not to mention findng a place to drill into the cab to run the extension, and then cutting the intake tube to make it fit onto the valve.
Seems like it'd be more work that gain IMHO.
what's the rise from the stock air box to the bottom of the windshield? i think he did all of that work for maybe 3~4 inches of depth....not a bad idea if he made a proper detachable snorkel with cover plate, i admire the work but think the effort isn't worth it....
