Thermal Barrier


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
  • ThermBar™ can also be applied to valve faces and stems, exhaust ports and combustion chambers
