If you lack the knowlegdge/talent to build one by yourself and you want a fairly cheap snorkle that looks really good and works really well, then go to
They sell an excellent full snorkle kit for $125. I have had one on my Zuk for the last year and it has saved my engine numerous times. The kit is extremely easy to install and well thought out. Its tough as hell(rolled my Zuk on the passenger side and the didn't even scratch the snorkle.) And it looks damn good. The people are good to deal with and they'll get it to you quick. Check the site out & good luck.
