PISTON (Hyundai HN19439-21110)

A worn piston can disrupt the compression cycle in a reciprocating assembly. This aftermarket replacement part references Hyundai as the OE maker and carries the cross-reference number HN19439-21110. The piston converts expanding gas pressure into linear motion through the cylinder bore. A failed piston may cause blow-by, reducing power output and increasing oil consumption. During a rebuild, technicians often inspect the piston for scoring or ring land damage. The item ships at approximately 1.195 POUNDS.
