DuraBowl^® Piston Reinforcement Partial Bowl-Edge Re-melting features:

• Extreme refinement of aluminum material structure created by localized re-melting using TIG technology
• Up to 4 times improved durability in high specific power engines compared to pistons without bowl re-melting.  Allows higly stressed combustion bowl shapes
• F-M DuraBowl^® process extends aluminum piston limits in the most challenging applications by increasing the fatigue strength (cycles) of the piston
