Is your Vauxhall or Opel with a 1.0, 1.2, or 1.4-litre petrol engine (like the A12XEL, A14XER, etc.) burning oil or losing compression? This 12-piece piston ring set is the OEM-spec replacement you need. The rings fit a 73.4mm cylinder bore and come in the correct thicknesses (two 1.2mm compression rings and a 2.0mm oil ring per piston). The set includes enough for a 4-cylinder engine. Made from high-quality metal, they're designed to restore proper sealing, reduce oil consumption, and improve engine performance. Compatible with many models including Corsa C/D/E, Astra H/J, Meriva, Combo, and more (check the full list). Always replace rings in a full set during an engine rebuild or overhaul. Ensures a proper seal for better efficiency and power. A crucial component for a successful engine repair job.
