Why Replacement Matters:

• Pistons are among the most highly stressed components within an engine and are fundamental to compression, combustion, and power production. Worn piston skirts, damaged ring lands, excessive clearances, or cracked piston crowns can reduce cylinder sealing and allow combustion gases to escape into the crankcase. The result can be reduced power, excessive oil consumption, increased blow-by, poor combustion, and accelerated internal engine wear.
• In performance applications, correct piston selection and installation are especially important. Incorrect piston-to-cylinder clearance, compression ratio, ring gaps, or piston-to-valve clearance can result in excessive noise, poor performance, overheating, cylinder damage, or severe mechanical engine failure.
