CP Radial Wall Low Tension Flex Vent Oil Ring - 4.140 Bore / 3.0mm / .150

This is the CP Radial Wall Low Tension Flex Vent Oil Ring, designed for a 4.140-inch bore. It's a key part of your engine's piston assembly, specifically tasked with controlling the oil that gets into the combustion chamber. Proper oil control is essential for preventing excessive smoke, maintaining engine health, and ensuring consistent performance.

This particular oil ring features a low-tension design and a flex vent, which helps it conform better to the cylinder wall. This improved seal means it can more effectively scrape excess oil off the cylinder walls as the piston moves. The radial wall construction adds to its ability to maintain tension and seal across a range of operating conditions. It's a well-built component for engines where precise oil management is critical.
