I want to share how I attacked building a snorkel... well kinda... the start of a snorkel. As in maybe the harder parts of getting ideas and hardware for the engine bay and good seals.

I have a weber carb on mine so i got the redline snorkel adapter http://www.redlineweber.com/html/application_guide/DGV_Snorkle.htm
Next I considered building my own air cleaner housing but after pouring over all kinds of air cleaner sizes and dimensions I decided to go with this K&N set up. I wanted a well made cleaner/housing and this seems pretty hardy. http://www.knfilters.com/universal/apollo.htm
Another solid option would be a UMP canister http://www.pacificcustoms.com/ump-air-filter-canisters.html
Beyond that you need a bracket to hold the air cleaner and a hole in the fender.
I built the bracket out of some 16g a and hole sawed a 4" hole through the fender.
I got some clean 4" exhaust tube from the local exhaust shop (just gave me a little scrap piece) to run through the fender.
Next needed to seal the air cleaner to the tube and went with a silicone tube that is for turbo/intake plumbing and such.http://www.siliconeintakes.com/hump-hose/

But... I'm not ready to go to the snorkel yet so I built a little scoop/ram air that will help me (Hopefully) on the freeway.

Pictures better then words

Toss your 2 cents in or use and enjoy

the intake is already that high, are you attaching something to it to make it a snorkel? as of right now, it is more of a cold air intake
