The top ring and oil ring assembly utilize stainless steel, providing resistance to corrosion and heat, while the second ring is crafted from ductile iron to maintain strength under high pressure. The gas nitride face coating on the piston rings reduces friction and wear, contributing to improved engine efficiency. The shallow groove design of the oil ring assembly ensures effective oil scraping without excessive oil consumption, maintaining proper lubrication and minimizing blow-by.\u003c\/p\u003e\u003ch2\u003eCompatible Acura and Honda Models\u003c\/h2\u003e\u003cp\u003eThis piston ring set is compatible with a range of Acura and Honda vehicles, including the Acura MDX, RL, TL, and TSX, as well as Honda models such as the Accord, Accord Crosstour, Crosstour, Odyssey, Pilot, RDX, and Ridgeline.
