The Sand Race Air filter The First Wet& Dry Air Filter in the WORLD

When I told you surprises were not over, I was being humble.

Thanks to the amazing work while developing the ULTRA4 Rally Raid Media, we could achieve the unthinkable:

an Air Filter that can adapt its use to the different conditions. NEVER was a product so complete and amazing in its efficiency!!!

The design of the complex matrix has been studied to achieve a superb performance while used DRY, no additional oil and easy to wash under water and a light soap in case of some "organic" contamination, insects or such.

But imagine that you decide to take your bike for a Desert trip, lucky you.

While riding behind some vehicles, most of the particle that would remain longer suspended in the air would be the lightest and smallest, below 10 microns.

In this conditions even paper filters, OEM, would fail, and here the amazing technology of the Rally Raid ULTRA4 filter media shows its incredible property.

While dry, the filter has a great 30 microns filtration capability, using a LIGHT OIL COATING, it will become THE best combination having both the smallest pore size to start from in a 3D deep matrix AND combining the adhesive property of the Air filter Oil.

Normally a Cotton or Foam filters would have pores the size of 200-450 plus microns, and only after a long period of accumulation of smaller particles would they start becoming a real air filter.
