Chevy Impala Performance Fuel Injectors, Fuel Rails & Components

Although the design of different fuel delivery systems may vary depending on the performance or purpose of the vehicle, all modern automobiles employ basically the same principal architecture. Fuel injectors, controlled by the ECU, receive the pressurized fuel from rails, which form a sort of a vessel incorporating a line of nozzles. Rails are separated from fuel lines by a fuel pressure regulator. And that’s pretty much it. Fuel rails and injectors, therefore, form the most important section of the system, which has a direct impact on the engine performance.

By upgrading these components, it’s possible to achieve a palpable output increase. The amount of additional horses that you can expect depends on the generation of your Chevy Impala. If it’s one of the B-Body generations with an early version of EFI system, then the upgrade will be highly effective. If it is one of the more recent iterations, then it is very unlikely that you can achieve any spectacular results. But anyway, the quality of the combustion process will be improved, which means that both fuel efficiency and power will increase. And with our Chevy Impala performance fuel injectors, fuel rails & components, it won’t be too expensive.
