    4" filter and IC strainer, not how but why?

    I have read the sticky on the bilge, 4" air filter and inter cooler strainer. The bilge I understand.

    But why the 4" air filter? Is there any performance gain over the stock intake? It looks like most run the kana flex up to the front of the ski, why is that? Why not just have it at the intake of the SC? What do you guys do with the stock intake box that runs along the side of the engine?

    And the strainer, why strain the water going into the inter cooler? What about the water going into the closed loop cooling system? I'm really confused on this one. Where is the inter cooler anyway?

    The 4" intake allows more air into the engine, more air = more hp. You have to think of your engine as a big air pump. So the more air you can get in the better.
    You could have it at the intake of the SC, but you risk water intrusion.
    You want to strain the water going into the IC so you do not clog it up with debri. A clogged IC is not an efficient IC.
    You do not filter the closed look cooling, because...............its CLOSED LOOP.
    If you tell us what year and model ski you have we will tell you where your IC is.

    Thanks for the reply Troy.

    I understand the cooling system is closed loop, but there must be some heat exchanger that cools the closed loop fluid, right? I assume it is cooled with sea water since there is no radiator.

    I have an 07 RXT 215.

    In your Rxt the IC is in the intake manifold. It works ok, but there can be pretty good performance gains from adding a larger external IC.
