2003 2004 2006 Ford 6.0L Powerstroke cold air intake by Green 2551. The Green Ford 6.0L Powerstroke cold air intake provides a 25 horsepower and 75 ft lbs of torque gain while helping to improve fuel economy. NOTE: Will not fit 2005 6.0L Powerstrokes. The picture shows this Green intake. Green Filters molded rubber shroud seal is designed to give you true cold air. With Green's design, the truck's air intake opening is sealed to the air box to prevent engine heat from robing you of horsepower and gas mileage. Green provides the little features that make the big difference when you want to make power and save fuel. Other filters use a simple pressure molded injection process to bond the perimeter rubber to the interior filter components. That method saves manufacturing time, but in the process, a considerable amount of rubber can seep onto the filtering surface. While it may not look like much, that spill-over rubber can restrict as much as 25% of the intended air flow. Green on the other hand, uses a time consuming, and costlier, 4-step production process which virtually eliminates seepage, and maintains maximum air flow through the filter. Green Filters are constructed with coated steel mesh for extra strength and durability. Steel mesh makes Green much more dent resistant and holds up to many more cleanings.
