When you are rebuilding an engine for performance, you have got to build a good foundation.
Teflon Coated Pistons are the base of that foundation.
Teflon Coated Skirts Reduce Horse Power Robbing Friction and Piston Slap
Less slap = less noise, less cavitation (or liner pitting) and means longer cylinder liner life.
Teflon is the slipperiest material known to man. With a film of oil on the Teflon we now have a very smooth riding piston in the liner
These pistons have Holes in the wrist pin bosses to improve oiling and superior lubrication.
Piston skirts are semi-fully coated for added protection against heat.
Oem Honda pistons only have 20 percent of the skirt coated.
These pistons are domed to match OEM Honda K20A2 PNC Piston.
40 Percent stronger than OEM Honda cast pistons.
These pistons have been tested to support over 250 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.
