Cold Air Intakes for the 7.3L Powerstroke Diesel. They are not all created equal. Do your research before putting one on your truck. Don’t sacrifice filtration that you need for flow that you don’t need. I run an S&B Dry Filter because it has great flow and great filtration efficiency. #coldairintake #sbfilters #airfilter #powerstroke #7tree #superduty #trucknation #fordexcursion #dieseltrucks #diesellife | Freedom Worx
