Yes, it might look more like a dog's chew toy but the innovative Funnel Web Air Filter implements a design that nearly doubles the surface area.

Instead of the traditional flat or smooth design, the MSR Funnel Web Air Filter uses a pyramid contour without increasing the actual size of the filter so it fits inside your current air box. The pyramid cut expands the surface area that traps dust and dirt while maintaining maximum airflow. It's a boon for off-roaders especially those who ride in dusty conditions.

The Funnel Web Air Filter incorporates a single-layer, single-density foam and uses an injection-molded urethane seal that provides a lighter and more precise fit. The urethane seal also reduces the chance of stretching when cleaned which provides a longer filter life and keeps the integrity of the seal intact. This filter should be oiled before installation.
