What Is a High Impedance Injector and Why Should You Use One?

Q: What is a high impedance injector?
A high impedance injector is a fuel injector with a coil resistance typically ranging from 12 to 16 ohms. These injectors are widely used in modern vehicles and are compatible with most stock and aftermarket ECUs. Their design allows for smoother operation, reduced electrical load, and easier integration without the need for additional resistors or driver boxes.

Q: Why choose high impedance injectors over low impedance ones?
High impedance injectors offer major benefits:

• ✅ Tuning Friendly – Easily recognized and controlled by most ECUs

• ✅ Safe for Stock Wiring – No need for resistor packs or peak-and-hold drivers

• ✅ Reliable Idle & Throttle – Great for street/strip setups and daily drivers

• ✅ Broad Compatibility – Works seamlessly with systems like HP Tuners, Holley EFI, AEM, and more

They’re ideal for performance upgrades that don’t want to sacrifice drivability for horsepower.

Q: Do high impedance injectors support big power?
Yes! At HighPerformanceInjectors.com, we offer high impedance injectors that flow enough fuel for builds pushing over 2000+ horsepower. From 1000cc to 2200cc and beyond, you can get serious flow with OEM-level control and stability.

Q: Are high impedance injectors compatible with E85 and other fuels?
Absolutely. Our injectors are E85-compatible and also work with pump gas, methanol, and race fuel. They’re tested for high heat and pressure environments, making them perfect for:

• LS swaps

• Turbocharged or supercharged engines

• Flex-fuel builds

• Drag or street applications

Q: How do I know which injector size I need?
Injector size depends on your power goals, fuel type, and engine setup. Here's a rough breakdown:

• 1000cc (95 lb/hr): Good for 600–750 HP on E85

• 1200cc (115 lb/hr): Great for 750–850 HP

• 2200cc (200+ lb/hr): Serious race setups pushing 1000+ HP
