Nitro-Port Cast, LS3 750 HP EFI System/ Short LS3 Port Intake/ Dual O2 Sensor/Cable Driven 102mm Throttle Body/ 55lb Injectors/ With Trans control

FiTech Fuel Injection proudly introduces the new Nitro-Port LS EFI Systems, combining FiTech’s cutting-edge EFI technology with the all-new Nitro-Port Series Intake Manifold. Designed for serious street builds and track performers alike, these complete EFI systems deliver reliable horsepower and modern drivability in one powerful package.

At the heart of each kit is the Nitro-Port cast intake manifold, engineered with a low-profile modular runner design, short runners for high-RPM performance, -8 AN fuel rails, pre drilled and tapped nitrous/water injection port, and support for 92mm, 102mm, and drive-by-wire* throttle bodies. Rear-mounted vacuum ports and MAP sensor location keep installations clean and streamlined. *Drive-by-wire throttle bodies coming soon.

Every Nitro-Port LS EFI System includes:

  • FiTech ECU
  • Complete wiring harness
  • Full set of sensors (including MAP, IAT, CTS, and more)
  • Dual Wideband O2 sensors
  • Touchscreen handheld controller for setup and tuning
  • And of course, the Nitro-Port intake manifold.

These plug-and-play systems take the guesswork out of EFI conversions while delivering exceptional performance and adjustability right out of the box.

Whether you’re swapping an LS into your muscle car or building a high-horsepower track weapon, the FiTech Nitro-Port LS EFI Systems provide the power, tuning control, and quality FiTech is known for.
