11251713192 BMW PISTON RNG

These rings sit inside grooves on your pistons, and their job is really three – fold. First, they seal the combustion process – basically, they make sure all that power from the fuel burning stays inside the cylinder to push the piston, instead of leaking past it. Second, they control oil. They scrape excess oil off the cylinder walls as the piston moves, preventing oil from getting into the combustion chamber and causing smoke or fouling spark plugs. And third, they help transfer heat from the piston to the cylinder walls, keeping things cooler. Think of them as the seals and scrapers of the engine’s inner workings. These rings are absolutely critical to engine performance. They’re right there in the heart of it, in the engine’s cylinders. They directly affect how much power you get, how efficiently your engine runs, and how much oil it uses. They’re part of what turns fuel into motion. If they’re worn, you’ll notice a loss of power, increased oil consumption, and potentially some smoky exhaust. Honestly, without good piston rings, your engine just won't run right for very long. They’re constantly under a lot of stress and heat, so they do wear out over time. When they do, you start losing compression, which means less power and reduced fuel economy. Worn rings also allow oil to slip past, leading to blue smoke coming from the exhaust, and eventually potentially engine damage. Replacing them restores compression, reduces oil consumption, and keeps everything running smoothly. You can often find complete sets—everything you need for a rebuild—at places like Fixparts Online. They’re a fairly common maintenance item if you’re doing engine work. You’ll notice if they’re going bad – usually a drop in power, or increasing oil usage between changes. BMW stands by its products: Piston Ring Set (MPN 11251713192) includes a 12-month warranty!
