Triggering & Communications:

Piston Dome Coating G09 00mm Exhaust Rally / RaceBenefits of Piston Dome Coating: Improved Heat ResistanceReflects combustion heat away from the piston, protecting the dome from thermal damage in high compression or forced induction engines. Reduced Carbon Build UpHelps minimize carbon deposits on the piston crown, keeping the combustion chamber cleaner and more efficient over time. Lower Operating TemperaturesPromotes better thermal management by reducing the amount of heat absorbed by the piston,
