This is a replacement ring set for the stock OEM piston stock bore 07+ LNF/LHU/LDK 2.0 liter direct injection engine.

A piston ring must have both spring-like tension and the properties to become a true circle when closed. In the combustion chamber of engine, NPR’s piston rings serve to seal combustion gas, control lubricating oil, dissipate heat, and prevent wear and seizure under the severe conditions of operation. Now that engines are required to be more compact, lighter, and more sophisticated in performance, the choice of piston ring materials has been widened to include steel in addition to the traditional cast iron. Moreover, in order to enhance their wear resistance and durability, they also undergo various surface treatments including nitriding and PVD treatment.

In these environmentally aware times, progress is being made in the introduction of low-emission cars for NOX and HC reductions and in the control of fuel consumption for CO2 reduction. To achieve these purposes, the following techniques have been developed and incorporated in the design of piston rings.

  • Piston ring combination for low-friction 
  • Thinner width compression-and oil control rings
  • Advanced surface treatments, and high-durability, low-cost materials
  • Optimum design through tuning techniques

Does not fit JE or Wiseco forged piston sets.
