Designed to sit under the grate, with adjustable rods to support the filter. Aesthetically pleasing, as the entire filter is hidden. This gives the filter a longer lifespan, due to no vehicle contact and limited UV exposure. The support bars are extremely durable and can be used with your next filter replacement.
