Benefits of Upgrading to Audi B5 S4 550cc Injectors
Increased Power and Performance
One of the main benefits of upgrading to the Audi B5 S4 550cc injectors is the increased power and performance.

Cost
Upgrading to the Audi B5 S4 550cc injectors can be expensive, with the injectors costing around $500. Additionally, the cost of tuning and upgrading the fuel pump must be considered.
