What is the primary function of piston rings?

Piston rings have a few key jobs. They seal the combustion chamber to maintain compression, transfer heat from the piston to the cylinder wall for cooling, and regulate oil consumption by scraping excess oil from the cylinder walls.

Are these rings suitable for a stock engine rebuild?

This HKS N16 piston ring set is designed for performance engine builds. While they can be used in some applications, it's best to confirm compatibility with your specific engine's requirements and intended use.

What does 'Not CARB approved' mean for shipping?

CARB (California Air Resources Board) approval is required for certain emissions-related parts sold in California. Since this part is not CARB approved, it cannot be legally shipped to addresses within California.
