FE Ford EFI-IR Kits
We engineer the components for our EFI-IR kits for each specific application, sourcing product from the finest manufacturers so you don’t have to worry about compatibility issues. Our kits include a HILBORN EFI-IR manifold, engine management suite, fuel system and synchrometer.
HILBORN EFI-IR Manifolds
HILBORN EFI-IR manifolds are not conversions, but are engineered at the foundry level to accept the EFI components. Our racing experience has taught us that one size doesn’t fit all, so we design each manifold around your specific application by picking the correct butterfly, fuel rail and injector nozzle size. Multiple butterfly sizes give us the flexibility to tailor the manifold to meet your horsepower requirements or drivability needs. All manifolds are finished in a protective clear anodize giving them the distinctive nostalgia grey color. Many other finishes are also available so be sure to check out our finish options page. As a True IR design, it does not have a plenum that is all the rage today. To read more about plenums and IR manifolds, visit our conversation titled “what is a true individual runner manifold?” on our FAQ page. Ram tubes made for your designated height top off the injection system you have always wanted.
- Application specific butterfly sizing (If available)
- True IR design
- Corrosion resistant hard anodized fuel rails
- Mounted TPS with pig tail
- Vacuum kit
- Protective clear anodized finish for the nostalgia grey color
- Finish options include polishing, powder and ceramic coating along with chromed ram tubes. See our finish options page for more information.
The heart of any EFI system is the engine management system. Today, the most requested feature is self-learning. Although this feature will help eliminate some of the manual tuning that was a requirement with older systems, it is not a perfect technology, so we only supply ECU’s that have lap-top access in order to fix troublesome spots that the self-learn alone cannot fix. We have learned that high horse power and race only applications will require more hands on tuning to extract their maximum potential.
As part of the kit we provide an IR specific base calibration, along with comprehensive technical support to answer any questions you might have. As this technology advances, we will continue to offer the latest in aftermarket features, integrating them into your system.
- Main, ignition and injector harnessing. Available fully terminated or unterminated.
- MAP sensor
- Coolant sensor
- Air Temperature sensor
- Wide Band O2 sensor
- IR specific base calibration
- Comprehensive technical support
Electric fuel pumps from Weldon High Performance have been a staple product with our kits since day one. As a supplier to the aviation industry, pumps from Weldon High Performance have proven themselves to be the most reliable on the market and have dispelled the myth that a frame mounted pump cannot be quiet. Along with picking the correct fuel pump for your application we provide the matching high flow Weldon regulator and HILBORN fuel filters. Installation schematics are included so you can design the rest of your fuel system correctly. Click to see fuel schematic #1, fuel schematic #2 and fuel schematic #3.
- Weldon High Performance fuel pump
- Weldon High Performance high flow regulator
- HILBORN primary and secondary fuel filters
- Correctly sized inlet and outlet fittings
- Installation schematics
Additional components provided in the kit for proper installation include a remote thermostat housing and a synchrometer for fine tuning the butterflies. Tuning and synchronizing the butterflies is an important part of a HILBORN EFI-R manifold installation. We provide detailed step by step videos of these procedures.

At HILBORN Fuel Injection, all we do is fuel injection! This focus has allowed our technicians to become experts in the field, providing the comprehensive technical support you would expect. Our technicians race, tune and install the very same systems you will purchase for your own vehicle, giving us the valuable advantage to help you succeed with your EFI system. At HILBORN Fuel Injection, our #1 goal is to make sure you have a great EFI experience.
The HILBORN Advantage
HILBORN Injector manifolds are a true individual runner (IR) manifold, providing the best all-around power output and drivability of any other induction system. To learn more about true IR manifolds, click here for our FAQ page.
A true IR does not suffer from the disruptive cylinder to cylinder reversion pulses associated with a common plenum intake or IR manifolds with a plenum chamber. These pulses promote fuel separation from the air carrier, the slowing of air movement in the manifold, and the inability to realize engine potential due to poor cylinder fill and burn characteristics in the combustion chamber. However, the IR design of the HILBORN manifold isolates these pulses, allowing the engine to make more bottom end torque, have increased throttle response and, most importantly, to accelerate faster. Most applications will also see a significant increase in top end power. Elimination of these reversion pulses is also responsible for our excellent low speed drivability, even with aggressive camshafts.
Enhanced engine performance and drivability all in one package? Yes, with a Hilborn EFI system on your car, you can experience a total transformation of your engine. It is possible to have the best of both worlds with a HILBORN.
