With a film of oil on the Teflon we now have a very smooth riding piston in the cylinder liner
Less slap = less noise, less cavitation (or liner pitting) and means longer cylinder liner life.
These pistons have additional holes in the wrist pin bosses to improve oiling and provide improved lubrication vs. OEM pistons.
Piston skirts are fully coated for added protection against heat.
40 Percent stronger than OEM Honda cast pistons.
These pistons have been tested to support over 350 WHP with the proper tuning and supporting mods.
Wrist pin center to dome height has been matched to within .001"
Dome displacement has been matched to within .005 CC
This results in near identical cylinder compression, yielding more horsepower and better efficiency.
Fits: Honda/Acura D16 Style engines.
