MAHLE Original Audi A4 05-02 Camshaft Seal

When you're diving into the top end of your 2002-2006 Audi A4 or A4 Quattro, replacing the camshaft seals is a smart move. These seals sit around the camshaft where it passes through the cylinder head, and their main job is to keep engine oil from leaking out. Over time, the rubber can get hard and brittle, leading to those tell-tale oil spots under your car.

Victor Reinz, a trusted name in sealing products, makes this camshaft seal. It's built to meet the original specifications, meaning it should fit right and do its job of keeping oil contained within the engine. Replacing these seals is often done when you're already in there for other work, like valve cover gaskets or timing belt service, making it a practical part to address potential leaks proactively.
