Review on 🔒 Fuel Gas Cap Replacement Seal for Volkswagen & Audi VW MK4 MK5 MK6 B5 B6 B7 B8 Petrol Gasket - RKX by Raul Fabijan

Fits perfectly on the existing Audi Genuine fuel cap. I didn't want to buy an OEC to avoid inconsistencies, so I replaced the O-ring instead. I took out the old ring and compared the thickness of the two and noticed a significant difference in thickness. Old after 10+ decreased in thickness by about 30% as expected. Installing a new ring gave the cap the required thickness and improved tightness in the gas tank. See photos of the old and new rings. There is a very noticeable difference in thickness.
