VW Audi 3.6L & 3.2L Engine Valve Cover PCV Valve Diaphragm Membrane Replacement

Is your VW or Audi with the 3.6L or 3.2L engine running rough?

Might be the PCV diaphragm inside the valve cover.

This replacement membrane is a direct fit for the factory part numbers 03H103429H, 03H-103-429 H, and 03H 103 429H.

It’s made from high-quality Viton rubber, which handles the heat and oil better than standard rubber, lasting longer and sealing better.

This is an aftermarket brand, but it’s a brand new part ready to install.

It goes right on the front of the engine.

If your PCV valve is rattling or you’ve got a vacuum leak, this cheap fix can save you from buying a whole new valve cover assembly.

Includes a manufacturer warranty, so install with confidence.
