Product Description

The Radium Engineering 20-0872 Fuel Rail is a premium upgrade designed specifically for the 1.8 T 20V engine found in many Volkswagen and Audi models (1996-2005). Its high-flow internal bore, billet aluminium construction and 8-AN ORB ports allow for robust fuel delivery even in heavily tuned or high-boost setups. Whether you are upgrading for better injector flow, higher power output, or more aggressive tuning, this fuel rail ensures that your injectors are fed consistently and securely.

Installation is straightforward: the rail uses factory mounting locations and includes the necessary manifold spacers to accommodate intake manifold variations. While plumbing and regulator hardware are not included, the 8-AN ORB ports offer flexibility for custom setups in both stock and aftermarket systems. If your 1.8 T 20V build demands higher fuel volume or more stable pressure under load, the 20-0872 is an excellent choice.
