✅ If the butterfly shafts, which regulate the air flow to the individual cylinders, break, loose parts can be sucked into the engine, causing extensive damage to the engine. With these metal butterflies, the risk of the butterfly breaking off and being sucked into the cylinder is avoided. If the seals are damaged, leaks and exhaust gas losses can occur, resulting in loss of power and increased fuel consumption. Translated with www.DeepL.com/Translator (free version) ✅ The size should be checked with the old ones, as some engines may have 22mm and others 32mm diameter. --【CONTENTS 📦】: For four-cylinder models : Four 0.86 inches (22mm) aluminium butterfly plugs and a fourteen-piece manifold gasket set: (4 x 11612246945 + 4 x 11617790198 + 1 x 11612245439 + 5 x 11612246949) -【OEM reference 🚗 】:11612246945, 11617790198, 11612245439, 11612246949 -【COMPATIBLE WITH 🚗 】: E87 E46 E90 E39 E39 E60 E61 E65 E83 E53 -【CUSTOMER SERVICE 👍AND WARRANTY】.
