Thermal Barrier

ThermBar™

A thermal barrier coating helps keep the heat in the combustion gases and out of the piston. Our ThermBar piston crown coating is a ceramic-metallic coating which reflects heat back into the combustion chamber and improves engine operation

• Helps reduce piston temperature and extend reliable part life
• Keeping the piston cooler can reduce skirt collapse in extreme running conditions
• 2 stroke engines can be tuned to run just slightly leaner for more power without damage
