MAHLE Original BMW 1 Series M 11 Engine Valve Stem Seal Set

If you're rebuilding the top end of your BMW engine, replacing the valve stem seals is a critical step. This set from Victor Reinz, part number SS46007, is designed to fit a broad range of BMW models, ensuring a proper seal between the valve stem and the cylinder head. Worn valve stem seals can lead to increased oil consumption, blue smoke from the exhaust, and fouled spark plugs, all of which can impact engine performance and longevity.

Victor Reinz valve stem seals are well-built to handle the heat and pressure within the engine. They are made from durable materials that resist degradation over time, helping to maintain a tight seal and prevent oil from leaking past the valve guides and into the combustion chamber. This is especially important for engines that see a lot of miles or operate under demanding conditions. Proper installation is key, so be sure to refer to your vehicle's service manual for the correct procedure.

This set includes all the necessary seals for a complete engine overhaul. Replacing these seals along with other top-end components can help restore lost engine performance and reduce oil consumption, keeping your BMW running smoothly.
