Made to high standards, these covers are designed to extend the life of your air intake filter while also giving you a way to visually see the amount of dust collected. The covers work equally well on both oiled and non-oiled filter elements to prevent larger debris from prematurely reducing critical air flow to your engine.
Installation Note: Take care installed over filter elements with metal cages as a metal snag can tear your cover.

What’s your diesel sucking on?
Clean air extends the life and performance of your 7.3 why risk being unprotected. Keep an extra one on board for those dusty desert trips!

Great Prefilter
I got this to handle our road dust in Arizona. After having worked at a major defense contractor, I found out we have terrible particulate in our desert atmosphere and that AZ is the preferred testing ground for proving in military equipment that is used in the sandbox (middle east). Knowing we live in the harshest dust environment in the USA led me to find a good prefilter and this one fits the bill at a decent price. THANKS!

6637 Replacement cover
This is a must for me since I live off a dirt road. I can already see what this cover has been collecting pre filter. Would recommend!

6637 REPLACEMENT COVER - BLACK
Very hard to install (extremely tight fit over the aFe Big Boost filter). Otherwise satisfied.
