DeatschWerks 01-09 Audi S4/RS6/S6/S8 4.2L 1000cc Injectors - Set of 8

These DeatschWerks fuel injectors are built with a 1000cc/min flow rate, giving you a significant increase over stock. They are sold as a matched set of 8, which is crucial for ensuring each cylinder receives the same amount of fuel. This consistency is key for smooth engine operation and optimal performance, especially when you're pushing your 4.2L V8 Audi S4, S6, S8, or RS6 beyond its original specifications.

DeatschWerks is known for its high-performance fuel system components, and these injectors are no exception. They are designed to fit directly into the specified Audi models, simplifying the installation process. While they offer a substantial flow increase, it's important to remember that upgrading your fuel injectors often requires a corresponding tune to properly manage the increased fuel delivery and prevent issues like lean conditions. This set is a popular choice for those looking to support more aggressive engine modifications or simply ensure their high-performance Audi is getting the fuel it needs.

When installing these, ensure you have the correct supporting modifications and a professional tune to take full advantage of their flow capacity. This set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation guidelines for the best results.
