Fuel Injectors Performance Parts & Modifications

Fuel injectors play a critical role in how your engine performs. Whether you're maintaining a factory vehicle, upgrading for bolt-on modifications, or building a high-horsepower performance car, the right injectors help ensure your engine receives the precise amount of fuel it needs across the entire rev range.

At Empire Performance, we stock fuel injectors for a wide range of applications, from direct replacement units through to high-flow injectors designed for serious power builds. As horsepower increases, fuel demand rises, and upgrading injectors is often a necessary step to support larger turbos, superchargers, camshaft upgrades, E85 conversions and custom tuning.

Choosing the right injector size is important. Too small and the injectors can become a limitation. Too large and drivability can suffer if the setup is not properly matched. Our range includes options suitable for everything from mild street upgrades through to dedicated race applications.

When Should You Upgrade Your Fuel Injectors?

One of the most common reasons enthusiasts upgrade fuel injectors is to support increased power levels. Factory injectors are designed around the vehicle's original output, and once performance modifications are added, they may no longer provide sufficient fuel flow.

Larger injectors allow the engine to maintain safe air-fuel ratios under boost and heavy load, giving tuners the flexibility to extract more performance safely. They are particularly important for turbocharged vehicles, high-compression builds, ethanol fuel conversions and engines running significant performance upgrades.

Fuel injectors can also become worn or clogged over time. In these situations, replacing ageing injectors can help restore smooth operation, improve fuel delivery consistency and maintain engine reliability.
