MINI Piston Ring Set - Genuine MINI 11257566479

Product Information

An engine piston ring set consists of multiple rings that fit into grooves around each piston. Their main roles are to seal the combustion chamber, regulate oil consumption by scraping excess oil from cylinder walls, and transfer heat from the piston to the cylinder wall. Typically, a set includes compression rings (for sealing combustion gases) and oil control rings (for managing lubrication).

• Excessive exhaust smoke (blue or gray), caused by oil leaking into the combustion chamber.
• Loss of compression and power, leading to poor acceleration and misfires.
• High oil consumption, requiring frequent top-ups due to oil burning inside the cylinders.

About Genuine Mini

The original parts used by Mini to build your car are available as replacement parts under the “Genuine Mini” brand. Manufactured under the direction of Mini, expect excellent quality and a premium price since these parts are exclusively available through the Mini Dealership network.

You may not realize this, but the parts that make up your Mini are not necessarily manufactured by Mini. No cause for concern, as Mini designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Mini for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mini parts box and find an OEM branded part inside, simply with the addition of a Mini logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
