Description
-
Piston and ring kitThe kit includes pistons with machined dimples and a ceramic coating that creates a turbulent boundary layer between the combustion chamber walls and the incoming air/fuel mixture. This improves combustion efficiency.
-
Hyperformance diesel pistonsThese custom-made pistons are designed to provide performance throughout the life of the engine. Benefits include increased horsepower and torque, longer oil change intervals, and longer life for lubricated bearing surfaces.
-
Reduced emissionsSpeed of Air technology can reduce emissions.
-
Improved fuel efficiencyIndependent commercial users have documented fuel savings of up to 25% or more.
-
Extended engine lifeSpeed of Air technology can extend the life of the engine and reduce service intervals.

These turbulators create a thinner, well-attached boundary layer between the air-fuel mixture, its flame front and the combustion chamber walls. This thin, turbulent layer allows the combustion flame front to burn much closer to the cool metal walls of the combustion chamber, thereby increasing overall combustion efficiency. The result is significant reductions in fuel consumption, reduced emissions, increased torque and horsepower, improved drivability and pulling power. Lower soot emissions translates to better engine longevity and fewer service intervals.
SOA’s Hyperformance pistons also includes the application of aerospace-proven thermal barrier and anti-friction coatings on the piston crowns and skirts, respectively. The thermal barrier coating retains heat in the combustion process, thus providing additional efficiency and power. The anti-friction coating minimizes abrasion and resistance for even more efficiency. The combined technologies of a Speed of Air Hyperformance piston provide documented and significant benefits with a distinct value proposition.
Lab tests as well as years of real-world operational field testing in a wide variety of applications confirm the results. Notably, DFC Diesel, an innovative industry leader and Canada’s largest diesel engine remanufacturer, has been independently testing SoA technology for nearly two years in more than a dozen Dodge, Ford and Chevy trucks. DFC’s testing has been so successful that this company is now offering an entire line of Speed of Air® remanufactured engines.
During testing, DFC Diesel observed fuel consumption reductions of 25% or more with factory tuning, an average of 5% increases in torque and horsepower, NOx reductions as high as 80%, and the ability to extend oil change intervals by 50% due to decreased soot and fuel dilution. Observed benefits also include reduced regeneration cycles, DEF consumption, and visible exhaust/opacity, along with noticeably smoother and quieter operation.
To manufacture these custom piston kits, SoA has licensed United Engine and Machine Co. (UEM), a leading manufacturer of pistons with over 100 years of experience and a well-earned reputation for quality. As a family-owned and operated company, UEM has in-house design, development and manufacturing capabilities that allow this firm to meet nearly every type of engine’s piston needs.
