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.
