CP Piston Lateral Gas Porting (Per Piston)

CP Pistons is known for making high-performance pistons for racing and street applications. This product is for their lateral gas porting service, applied per piston. Gas porting helps improve the seal between the piston and cylinder wall by redirecting combustion gasses. This can lead to better ring seal and reduced blow-by, especially in high-performance engines.

This service involves machining small ports into the piston crown. These ports allow high-pressure gases above the piston rings to escape into the combustion chamber. This action helps push the piston rings more firmly against the cylinder wall, creating a tighter seal. A better seal means less unburned fuel and air escaping past the rings into the crankcase, which can improve efficiency and power. It's a detail often found in serious engine builds where every bit of performance matters.
