baff 10 Posted February 19, 2019 Hi guys, Does anyone know why does the air breather for a 2.0 16v 9A (the one that connects directly in the main intake air duct and with the ISV air line) wich is slightly "s" curved, has a tit? I don't have anything connected to that tit and from my searches is suppose to have a restrictor/choke. Here is the part I am talking about: https://volkswagen.7zap.com/en/rdw/corrado/cor/1993-76/1/133-36040/#20 drawing part no:20 051 133 997 B 027 133 997 S https://www.volkswagen-classic-parts.de/en/saugschlauch-golf-16v.html Quote Share this post Link to post Share on other sites
