S&B's new cold air intake kit upgrade for the 2011-16 Ford Powerstroke 6.7L is now shipping. Now featuring a redesigned one piece air box with S&B's signature large clear lid. Our intake tube is designed to minimize restriction and utilizes our new and innovative silicone tube seal that compensates for engine movement while still providing an effective seal against unwanted engine heat. Each intake kit is available in your choice of either cotton (cleanable) or dry (extendable) filter media.Diesel engines consume air at a much higher rate than most gas vehicles. The speed of air flow is referred to in cubic feet per minute (CFM). The higher the CFM, the more difficult it is to stop the contaminants from reaching the vehicles engine. S&B designed a filter specifically targeting the diesel marketplace using 8-layers of cotton, a proprietary oil formula and 30 years of experience making filters. The result is a Performance Air Filter that greatly improves the air flow while still protecting your engine. S&B's minimum requirement for efficiency on diesel filters is 99.1%.
