I am working on the FUELATV intake for the KFX450. Initial dyno runs have shown big gains. The new intake tube is designed, the billet adaptor is done. I have run the prototype filter. I still need to dyno a couple more filters. The first runs were done with my custom designed LTR450 filter. It worked great and the KFX may use the same filter, but i want to run a larger one to see how it does. ***** NOW **** for the real question. I am almost 100% sure that i will be able to make a new aluminum air box that will provide PLENTY of air for the intake. This box will not have a top, but it will have a back, bottom and sides. We will be doing final dyno runs soon. So if i can make a new air box that makes as much HP on the dyno as no air box what one would you want?

Here is a basic idea of prices. nothing is set in stone, but this is a ruff estimate to help make a decision. Count on this intake giving a dyno proven 3+ HP

FUELATV intake with aluminum air box - $259.99 - $299.99

FELATV intake with no air box - $229.99 - $259.99

Below are photos of my LTR450 intake. Just to give you an idea of the quality .......

i would go with the airbox myself, also i was wondering because i want to design an all new kind of airbox basically with aluminum and then have some sort of mesh walls that would keep out dirt but also allow the quad to get mucho air...sound like a good idea?
