1000cc Cadillac CTS-V - LSA Fuel Injectors

Upgrading your Cadillac CTS-V LSA with 1000cc fuel injectors is a game-changer for performance enthusiasts looking to support higher horsepower, better fuel delivery, and improved engine efficiency. Whether you're adding forced induction, running E85, or simply need more fuel flow, the right injectors can make all the difference.

The factory injectors on the CTS-V LSA engine are designed for stock performance, meaning they can quickly become a bottleneck when upgrading your engine for more power. Here's why a 1000cc injector upgrade is essential:

• Supports Higher Horsepower – Ideal for builds pushing more power, whether through superchargers, turbochargers, or aggressive tuning.
• Compatible with All Fuels – These injectors feature stainless steel internals, making them resistant to ethanol-based fuels like E85.
• Optimized Fuel Atomization – Provides better fuel delivery and combustion efficiency, improving throttle response and overall engine performance.
• Direct Fitment for CTS-V LSA – No need for complicated modifications—these injectors fit directly into your factory fuel system.

Specifications & Features

When choosing fuel injectors, it's crucial to understand their specifications to ensure they match your performance goals. Here's a breakdown of the 1000cc Cadillac CTS-V LSA injectors:

• Testing Data Access: Yes, so you can verify the flow and performance of each injector

Installation & Tuning Considerations

Upgrading to 1000cc injectors requires proper tuning to maximize performance and prevent issues like running too rich or lean. Here's what you need to know:

• Professional Tuning Required – Larger injectors require ECU recalibration to optimize fuel delivery and air-fuel ratios.
• Check Fuel Pump Compatibility – Ensure your fuel pump can support the higher fuel flow to avoid pressure drop.
• Direct Fit, No Extensions Needed – These injectors install directly into your Cadillac CTS-V LSA without modifications.
