The oil enhances filtration efficiency without restricting air intake, keeping your Yamaha's carburetor or fuel-injected system optimized for peak throttle response right out of the box.

- Washable and Reusable: Built to last race after race. Simply clean with Twin Air Filter Cleaner/Skinny Spray, re-oil, and reinstall – extending the filter's life far beyond disposable paper alternatives and saving you money in the long run.
- Lightweight and Durable Construction: Precision-cut from high-density foam for a glove-like fit in your Yamaha's airbox, reducing weight while withstanding extreme abuse from mud, water crossings, and high-speed jumps.
