Thanks RAMTX and Platinuminjected.
There is great side benefit to this mod. I park in a gravel lot with semi's going by every 5-10 minutes, so get a lot of dust on my truck, which as soon as I start it, is transferred to the dash, seats, etc. I have to clean my interior every day or 2. Now that I have the filter, I haven't cleaned the interior in 2 weeks, (other than vacuuming the floor mats) and it's still good.
