The Biggest and Best 1.6 Ecoboost injectors - available now!

What sets Nostrum apart:

  • Upgraded direct fit injectors ready for drop-in installation
  • 60% increase in flow
  • Double teflon seal for reliability
  • 240 Bar capable with optional pressure sensor!
  • Limited lifetime warranty  

The big ones are finally here! Push the limits of the 1.6 with the largest DI injectors on the market. Flowing a massive 60% more fuel than the factory injectors, these allow you to run full E85 and make more peak horsepower than ever before - without the need for auxillary or port injection. Friends don't let friends do meth!

Complete your Nostrum Fuel System and gain more injector headroom! While it’s known that the factory HPFP is not sufficient when trying to make additional horsepower, did you know that the factory fuel rail sensor is also a limitation? It is incapable of reading pressures beyond 20MPa, so to get the most of your upgraded fuel system, it is necessary to replace the factory sensor with the Nostrum Fuel Rail Pressure Sensor to read the full 24MPa (240 Bar, or 3480 psi) that the Nostrum HPFP and Injectors are capable of. Going from 200 to 240 Bar results in an additional 10% increase in injector flow!

Every Nostrum manufactured part is backed by a limited lifetime warranty. Our products are comprehensive solutions that come complete with everything you need inside the box, including detailed installation instructions. Tuning guides are also available for your dealer or tuner. We have customer service and calibration engineers on staff to provide you with any support that you may need, from installation to tuning.

*Horsepower and Torque numbers are approximate and can vary significantly depending on numerous factors including what supporting upgrades are done to the vehicle, ambient temperature, elevation, road surface, tire selection & condition, fuel octane and quality, vehicle weight, and more.  The advertised numbers herein are based on optimal conditions and utilizing proper supporting modifications.  Your results may vary. 


  • I see a lot of mentions about OEM equivalent spray patterns. What does that mean and why is it important?

While increasing flow rate is critical to making more horsepower, there are other factors to consider when choosing fuel system upgrades. A bigger injector isn’t always a better injector! It can flow a large volume of fuel at WOT, but if the spray pattern is poor, you can expect poor idle quality, poor drivability, increased knock propensity, soot, NVH (noise vibration harshness,) and tuning difficulty. Additionally, the wrong spray pattern can result in liquid fuel impinging in the cylinder walls, causing oil dilution, which increases mechanical wear to internal engine components.

Nostrum has invested significant time and resources into acquiring the equipment and machinery necessary to deliver an OEM level of quality on our injectors. Our spray patternation and arc flash machines (images below) give us an unparalleled look at how an OEM injector is designed and how it operates.  Our engineers design and develop injectors to optimally interact with engine air flow inside the combustion chamber to improve fuel evaporation and create a homogenous air-fuel mixture that results in a higher combustion quality. For you, this means that you can expect our injectors to perform at their absolute best regardless of what you are asking from them, from daily driver duty to setting new ¼ mile records.
