Air filter kit
It's a awesome air filter kit for your old 7.3 powerstroke trucks. If you want some then the stock air box this kit is differently something you should buy with the high quality air filters from donaldson they have longer life to them over stock and more easy to maintain.

Huge improvement.
Takes some cutting to get it to fit. At least doubles the size of the filter.

Easy install, just removed the stock box and dropped this in. Way more air flow, you can really hear the turbo breathing now.
