Donaldson replacement air filter
It's an air filter. Undamaged and exactly what was already on the truck. Minimal tools and time to swap out.
The entire kit was the same, simple and quick.
I would not ever run it without the outerwear skin but it probably says that when you purchase the "kit" package. -

Best easy modification I can do to my 7.3 power stroke. Riffraff makes it easy with their kit. Best investment ever.
I've been purchasing from Riffraff for a while now for my 7.3 powerstroke and I can truly say that their prices are reasonable. Every time I order from them I receive my product within a reasonable time. I will be their loyal customer.
