Show original supplier description
The Firad 1043HF injector nozzles are performance upgrades designed for a range of 1.9L and 2.0L 8V PD TDI engines from Volkswagen, SEAT, and Audi. These nozzles replace the stock units and provide significantly increased fuel flow, with options available for +50%, +80%, +100%, +120%, +160%, +200%, and +220% over original specifications. This enhanced flow is crucial for achieving higher horsepower figures in modified TDI engines. These nozzles are compatible with numerous VAG engine codes, including those found in models like the VW Golf Mk4 and Mk5, Bora, Jetta, Passat, Touran, Polo, Sharan, and Transporter. They also fit various Audi A3, A4, and A6 models, as well as Skoda Fabia, Octavia, Superb, Roomster, Seat Leon, Toledo, Ibiza, and Alhambra variants. The product is sold as a set of four nozzles. Achieving power outputs ranging from 250 to over 400 horsepower is possible with these Firad 1043HF nozzles, though it's important to note that such gains are contingent upon the installation of several other performance parts and accessories. The product is listed under the Engine and Fueling categories, highlighting its role in optimizing the fuel delivery system for performance applications.
