MAHLE Original Audi A4 06-97 Engine Valve Stem Seal Set

These valve stem seals are made from a durable fluoroelastomer material, which is known for its resistance to heat and oil. This is important because valve stem seals work in a high-temperature environment right next to the exhaust valve. When these seals start to fail, you'll often notice blue smoke coming from your exhaust, especially when you first start the engine or after it's been idling for a while. This happens because oil is leaking past the valve stem and into the combustion chamber.

Replacing your valve stem seals can help restore proper engine compression and reduce oil consumption. This set includes all the seals needed for a complete engine overhaul, ensuring that each valve is properly sealed. They are designed to fit a variety of Audi, Volkswagen, and Porsche vehicles, making them a solid option for many common engine repairs. Proper installation is key to ensuring these seals perform as intended and last for many miles to come.
