Clear cover to fit over the air intake on the Beta evo. This eliminates any mud or water coming in from either the side, between mudguard and sub frame and from the rear, it is shaped to mirror the contour of the mudguard but fits inside the sub frame so completely blocks all area except the front where ample air is allowed in for good engine performance. this does not affect engine performance at all. it is clear for easy inspection of the filter. Access to the filter is also quick and easy There is a hole drilled for access to the rear filter bolt and the front just lifts out of the way. Perfect for the ssdt.
