The latest snorkel on my Hummer H1 is a Sy-klone precleaner, with 12" extension and adapter. The extension is to protect the truck from bow waves that wash over the hood during deep water fording, while the precleaner ejects larger particles before they reach the air filter. I bought the precleaner and extensions/adapters directly from Sy-klone.
These pictures were taken in the winter, and my truck needs a wash - think they use enough salt on the roads
here in NH?
