I have seen the Patrol doctor system, where the they use a stainless snorkel and airbox fitted close to the passenger firewall. Maybe have a quick search online to see if they suit your needs.

I have no idea of their quality or customer service.
Personally, I don't like the idea of a stainless steel pipe mounted next to the passenger.
