It will reduce lower rpm torque and increase higher rpm hp. But it will fit, it's just reshaped into more of a cone shape.

You can just use the 05 airboot while retaining the 04 airbox. It is the main factor in the differences in power. It will bolt right up.

The boot is far from being the main factor of the 05's power. The reshaping of the combustion chamber and intake port is the controlling factor. Magazines feel it's better to spoon feed you simple ideas so you can follow along. :cry:

exactly! If you went to the dealer show last year, they had a cut away of the 04 vs 05 cylinder heads on the 250F. That is where the power is coming from.
