Early cars require the 20mm Valve Cover Breather Hose (06A 103 221BH) and Early Block to Intake Manifold Hose (06A 103 221BQ). These kits either replace or update the breather hose system. Some hoses are replaced and others are eliminated due to redundancies. This kit will simplify the breather hose system to function how it should with less complexity. Volkswagen made many variations to these breather systems, we have done our best to supply as complete of a kit as possible, but some revisions we have not seen and some customization may be required to make the kit fit on your specific year and revision.
