MAHLE Original Audi A4 08-06 Spark Plug Tube Seal

If you're working on your 2005-2009 Audi A4 Quattro and need to replace the spark plug tube seals, this Victor Reinz part is what you're looking for. These seals sit around the spark plug tubes to keep oil from leaking down into the spark plug wells. When they start to go bad, you might notice oil fouling the spark plugs, which can lead to misfires and rough running.

Victor Reinz is a well-known name in engine gaskets and seals, and this spark plug tube seal is made to fit right in place of the original. It's a simple rubber seal, but it's critical for keeping your engine's ignition system clean and dry. When you're pulling the spark plug wires or coil packs to get to the spark plugs, it's a good time to inspect these seals and replace them if they look cracked, brittle, or are leaking oil.
