Innovative high performance piston skirt design that provides:
1. Smaller piston to bore clearance
2. Less noise
3. Better ring seal
4. Higher power
5. Durability
Features:
Anti detonation grooves: protect the top ring by disrupting detonation waves and reduce piston-cylinder contact in high temperatures and engine RPM conditions.
Accumulator groove: accumulates residual combustion gasses reducing top ring flutter and improving seal.
Pin oil lubrication by broaches and oiler to reduce friction and increase durability.
