I think that you would have been better served to have retained the OEM filter canister and added a Safari Snorkel. The OEM canister can be fitted with a K&N element or a TRD element for street use and an OEM paper element can be easily dropped in for dusty conditions. In addition you would be pulling in significantly cooler air than the 180+ degree stuff thats floating around the engine compartment.
Just my preference, of course.
Oh, Going for a swim with the current set up would be interesting. Go to the homepage and refresh it till you see the gummer's 80 skinny dipping, Yours could hydro-lock and break rods and stuff.
