Genuine Mazda 3, Mazda 6 & CX-5 2.0 Piston Rings - PEY111SC0 are an important engine component, fitted to the piston to ensure a tight seal between the piston and cylinder wall, helping maintain optimal compression during the fuel combustion process.

This product is a genuine Mazda spare part, manufactured to high standards with exceptional precision, good heat resistance and wear resistance, ensuring long-lasting performance. The ring set typically includes a full set for 4 pistons for the 2.0 SkyActiv-G engine.
