Speed of Air Piston & Ring Set (0.25MM OVER) - 2008-2010 Ford 6.4L Power Stroke
Part # XA7205-0.25K1
Speed of Air's patented engine technology creates a drastically more efficient combustion process which results in a number of closely related benefits. Our technology creates sufficient lean burn to significantly reduce NOx while also reducing CO and HC emissions. Because more fuel is being completely burned in the combustion chamber, fuel consumption is decreased per Brake-Specific Horse Power. Likewise, available horsepower and torque are increased per specific fuel consumption. Finally, the reduction in carbon deposits—which resolve as soot in the engine oil—allows for extended oil change service intervals while prolonging the life of all lubricated bearing surfaces.
Speed of Air Hyperformance diesel pistons are proudly manufactured under license by United Engine & Machine Co. Every set of Hyperformance Pistons is custom made under the strictest quality control processes in the industry and designed to provide you unparalleled performance over the life of your engine.
