Air filters

So I've been waiting until the 20 hour break in period (which I still haven't reached) to get the 20 hour service done before I upgrade to the Yoshi X Vortex set up. Been reading a lot of previous threads on here regarding air filters and from what I gather apart from the FCI setup, it seems to be a personal preference sort of thing. With the quad in stock form, is there any air filter that provides better performance that doesn't require any additional modifications such as fuel programmer etc.?

You could buy a ProDesign filter setup however, you would have to use your stock air box, lid, intake, and exhaust with spark arrestor in. Change anything else with the FI bike and you will be very lean!

FCI with a FCI or K&N filter. If you don't want to upgrade intakes, slap a UNI on it and call it good.[ThumbsUp]

The fci is a over priced POS.
I can't stress it enough.
The thing is a cheap plastic tube, a chinsy folded plate that requires you to drill holes in your frame because they didn't feel like lining it up with oem holes, and crap "box" that lines up with nothing and just has huge gaps all around.

But it's been proven to work and be the best. So I pretty much have to run it.
Not happy with it one bit, but it works and that's all that matters in the end.

Could you be kind enough to send me a link for the Prodesign setup? And is the adapter plate necessary for that filter?

Bang for buck the pro design is the best intake around. It seals off the intake where its plastic and rivets stopping dust from going through. Been running mine since 05.

I would wait though until you put on your pipe and stuff to do this upgrade. To do the ais delete, everything will have to come apart. So may as well do it all in one go and be done with it.


Also these machines are lean enough from the factory even with the lid on the airbox the stock ECU might be too lean.

The ProDesign filter is a rebranded Uni Filter like the GYTR is.

Crap. I couldn't get the guy to get me one. He was to busy with his move and weeks turned to months.

FCI is super popular, they make great #s, however I tend to agree with the price and quality issues and run something else on my Hondas. I sell the Pro Design and other intakes as well and members can use coupon code: yfzcentral
