If your BMW with an N55 engine is throwing codes, idling rough, or has oil leaks near the valve cover, it might be this crankcase vent hose. This replacement fits a ton of BMW models from 2011–2017, including the 135i, 335i, 535i, X1, X3, X4, X5, and X6.
It's a direct replacement for OEM part numbers 7584128 and 11127584128. Made from durable materials to handle heat and engine vibrations.
Installation is pretty straightforward if you're comfortable working under the hood—just swap out the old hose for this one. No special tools needed, but a basic socket set helps.
Fixing this hose can improve engine performance, reduce oil consumption, and clear those annoying check engine lights. Always double-check your vehicle's exact model and year before ordering.
Keep your BMW running smooth and efficient. Your engine (and wallet) will appreciate it! 🚗
