If you are using a safari snorkel you can make it work. It comes with a lot more hose than you need, and you will need to modify the inlet end of the airbox and clamp it down tight. not a big deal. Hardest part for me was cutting into the metal for the first time. Oh, you will also need to relocate a couple of things a little lower on your inner wheel well in order to make room for the snorkel.
I think that you will find that any snorkle that you purchase will be quite expensive and will require a considerable amount of modification in order to make it work and look good.
A home made snorkle will be much less expensive and is exptemely easy to make. Mine is made from light-weight seamless pipe, a Tracel intake hose, a lenght of rad hose from a detriot diesel engine and the top off the intake from an old air compressor. Including the pipe bending, this snorkel cost me about $22.
It actually looks and works excellent .... email me if you would like a picture at firstname.lastname@example.org
That snorkel does look good. I am a metal man myself, so I could get some 3 inch light weight steel pipe and mandrel bend it and have an all steel unit. I am also thinking about finding an air filter box off a tractor that uses the very large air filters and can be located anywhere that you want.
Grabbed this off a 93 UD/Nissan 1300 box truck at a near by yard - $10! The angle of the picture makes it look huge, it's not really. It had one of those great bib air boxes - no room on the 4-Runner for that. I have yet to mount it, either.
