The S&B Cold Air Intake for 2011–2016 Ford F-250 and F-350 with the 6.7 Powerstroke flows 36.98% more air than the stock intake at 99.54% efficiency. Because it keeps the factory MAF sensor location, your ECM reads no changes, triggers no codes, and needs no tune.
The S&B high-flow intake replaces your stock airbox and inlet with an engineered system that moves more air, cooler, to your turbo. The fully enclosed airbox keeps engine heat and debris away from the filter, while the large-diameter inlet tube cuts intake restriction for faster throttle response under acceleration. You choose an oiled cotton filter, which is washable and reusable, or a dry filter for dusty environments, and the system offers multiple airflow configurations.
The airflow numbers are flow-bench verified at 580CFM rather than estimated, so the 36.98% increase and 99.54% filtration efficiency come with no tradeoff between airflow and filter performance. In the box you get the enclosed airbox with lid, the inlet tube, your chosen high-flow filter, all mounting hardware and clamps, and installation instructions, so there's nothing extra to source.
It fits Ford 6.7L 2011, 2012, 2013, 2014, 2015, and 2016 F-250 and F-350 pickups, all trims and box lengths, and does not fit Cab & Chassis trucks. Installation is bolt-on with basic hand tools, no cutting or drilling. Standard shipping takes 4–8 business days and express 2–3, with additional freight to Alaska, Hawaii, and some Canadian locations. There's a 30-day return policy on unused kits; once installed, returns aren't accepted. Tech support is included.
