About our 1000cc Corvette LS3, LS7, LS9 Fuel Injectors

When upgrading your Chevrolet Corvette LS3, LS7, or LS9, one of the most crucial components to consider is your fuel injectors. Whether you're increasing horsepower, running a forced induction setup, or simply ensuring your engine receives the right fuel flow, 1000cc fuel injectors are a solid choice. But are they the right fit for your build? Let’s break it down.

Why Upgrade to 1000cc Fuel Injectors?

Your Corvette’s stock fuel injectors are great for factory performance, but once you start modifying your engine—especially with turbochargers, superchargers, or aggressive camshafts—you’ll need more fuel flow. That’s where 1000cc injectors come in.

However, if you're planning forced induction, higher boost levels, or aggressive NA builds, upgrading to 1000cc fuel injectors is a smart move. With stainless steel internals, all-fuel compatibility, and included tuning data, these injectors provide a reliable and efficient solution for high-performance applications.
