Pistons w/ Rings fit 02-06 Nissan Altima Sentra 2.5L QR25DE. A piston is a cylindrical piece of metal that moves up and down inside each cylinder, compressing the air-fuel mixture and capturing the force created by the combustion process. This force is then transferred to the crankshaft, via the connecting rod. Symptoms of a Bad or Failing Piston include engine misfire, excessive oil consumption, knocking or slapping noise from inside engine. Be sure to have your engine pistons replace with our aftermarket replacement pistons as soon as they start to give you trouble.
