YFZ450R
Yamaha 09 YFZ450R YFZ 450R Air Box  $199.95

All CFM Performance products are proudly MADE IN USA.

Will fit 2009 and newer Yamaha YFZ450R and YFZ450X.

Premium features include: high strength 1/8" thick extruded aluminum brackets, not thin sheet metal brackets like the ones found on the other air boxes.

We build all of our air boxes with 5052 series aluminum for high strength, good looks, and superior corrosion resistance.

Our air box is designed to use a 4" flange I.D. filter. The reason we chose this filter is because it has an opening 6% larger than the stock filter, or any other filter available for the stock air box. As we all know, more air equals more horsepower.

Does not come with filter.

The CFM Yamaha YFZ450R Air Box is designed to use either UNI or K&N Filters.

Uses UNI filter part number NU-4102ST or K&N part number HA-4250.

Standard features on this air box include a removable lid, provisions to allow the use of your stock drain boot, and the stock crank case vent tube. There is not a better air box available for any price.
