    Do I really need a filter for my new air intake?

    I built my own 4 inch air filter intake for my GTX, basically copied whatís already out there. And I started to think, do I really need that restrictive air filter at the end of this tube? Sea Doo doesnít use one, and now Iím thinking for my RXT-X using a 90 degree angle and maybe a mesh screen at the end, just in case. Iíve done some research and havenít seen anyone do this before. The engine is basically in a sealed compartment, no dust storms to think of. And maximum amount of air.
    Any thoughts why I should use an air filter? Maybe that filter isnít as restrictive as Iím thinking.
    Thoughts?

    None needed, except for piece of mind.
    Yes it has been done before.
    I can tell you from personal experience, that it with a good quality filter, performance will be the same as with no filter.

    I wouldnt nessessarily run a actual filter,BUT i would use some stainless steel screen across the opening...Some members will tell you there is no need to run anything BUT I run a rear air intake on my ski and i can show you pics of cottonwood particals and other air born particals sitting on top of the screen..IF i did not have the screen in place,that debris would go through the Scer and into the ICer......BUT this is me and my preferance and others wil chime in and state thiers...

    I ran a 4inch diameter opening K&N, round, approx. 6 inch diameter filter media with 12 inch of filter length. It was the largest/highest surface area I could find, yet I still lost a few hundred rpm compared to running without it. Back to back, I'd gain rpm without, lose with it. I run a stainless mesh filter now. It catches the larger items, feathers, pieces of zip ties, lost sockets bouncing around the hull, etc. I haven't compared back to back with it vs. no stainless mesh filter. I will once my fuel pump/idle control arrives.

Maybe that filter isnít as restrictive as Iím thinking....Yes, it is.

    I understand the want for that pre-screen...especially in Greece...but it's restrictive as well.
