Yamaha Raptor 660 Aluminum Air Box
Our high flow aluminum air box uses a k&n clamp on design air filter. For optimum performance and protection. Our air box is better than the stock, partly because the stock air filter is difficult to install and has a tendency to fall out of place while riding allowing dirt to be sucked into the engine un-knowingly, causing damage over time. These air boxes also give you unrestricted air flow to the motor, giving you a 3-5 h.p increase that you can feel (with proper jetting). With the k&n filter we use, you do not have to worry about the filter coming loose while you are riding. Our air boxes are fully tig welded with h.d brackets. The Raptor air box also has two access holes in the front lip, so it is easier to get to the air filter clamps. We also include complete instructions. No modifications needed to install this air box, re-jetting will be required. This box is offered with or without a lid. The lid is similar to the LTZ400 lid design. Recommended k&n filter # ru-4710.
Yamaha Raptor 700r air box
This is our new design air box for the raptor 700r. This air box has a custom billet aluminum intake. Designed to use a larger diameter inlet air filter. Which allows for alot more air flow to the motor. This additional air flow gives you that extra horsepower you have been looking for. The air filter needed for this air box is a k&n ha-4250. Or a stock replacement Honda 250r air filter.
