    Air Intake on T3 RXPx 260

    I'm sure there a are a lot of threads on this subject - looking for ideas. I purchased 7 ft of 4" Kanaflex hose from Jerry. I had previously purchased the Riva iS rear power filter with a couple of ideas in mind which haven't worked out (then bought the Kanaflex). I thought I could use the iS plastic ducting to go over the engine and tube back to the front (I really want to be up front with my air intake) or turn it sideways to allow tubing under the manifold. So far nothing is working great. I tried today to thread the Kanafex under the manifold. I've not been successful in getting that stuff under the intake and back up and over the gas tank. Not sure what all is holding it under there but its tight! Mine is a 2012 model in case it matters.
    Does the Riva power kit for the T3 hull use a smaller ducting? Right now I have a bunch of stuff and don't like anything I've tried yet. Haven't opened the hardware for the rear air so maybe I can return or trade it but for now just want to get something working that I like.

    Wondered what seems to work best for everyone.

    Thanks for any ideas!

    Here is what I ended up with and I love it. All 3.5" thin wall aluminum tubing and standard silicone couplers.

    The air inlet bell came from ebay with a screen made from a Walmart colander.

    I like that idea - can you still get to your oil file cap? How do you have it hung up front? I was worried about the heat over the engine - I see you wrapped the tubing. Do you have the parts list (other than the filter which I can come up with).

    Thanks for the reply!

    So is everyone else able to get that 4" Kanaflex hose under and thru back up onto the gas tank side without removing the floatation?

    The oil cap is tight but it will sneak out.

    Most everything came from http://www.siliconeintakes.com/

    I don't recall where I got the 4" adapter for the blower.
    From there I did is 4" to 3.5" 90

    this is what that looks like

    I did a 30 silicone bend going into a 3.5" aluminum bend

    here is what the air intake looks like up close.

    Yes, you can run the Kanaflex under the intake and over the gas tank. I think I shaved about 1/2 inch off the foam to easy the install but it took me about 5 minutes to do that. Getting the stock airbox out was harder than running the kanaflex...

    I ran this set up all year in 2013 and loved it. I ride fresh water and even in aggresive turns it was OK. NO if your gonna wave jump NO. BUt in most everyday ridding I found no issue's what so ever, but the best way to get cool fresh air. You will notice it is paired with my NEW Fizzle 1000 IC.

    I had a situation where my ski went completely under water and came up inverted but still running. Having the intake air coming directly from the outside can be a huge issue on a bad day.

    That sounds like one of those things not covered under the 'Acts of God' section of the owners manual.
