The main reason for the dust issues on these vehicles is the sealing edge of the filters. Rubber seals on plastic are not the best option when used in dusty conditions. Plastic air boxes warp out of shape when they heat up. Rubber does not warp the same way. As a result the rubber seal does not compensate for the plastic going out of shape.
The GSL/UNIFILTER High Performance panel filters use two layers of foam. The outer layer is the work stage and the inner layer is a back up stage. Effectively it’s two filters in one. Foam is also the best filtering material for dusty conditions. When the correct oil is used on foam filters they will continue to breath and filter, even when dirty.
If you combine this with a 200 series GSL stainless airbox, the more rigid structure will remove any flexing, and this filter will help it all breath much better.
