- Easy to tune (by qualified tuners)
Unlock some of your LTG's hidden potential with Nostrum's High Flow injectors! Our High Flow Injectors have been designed and tested to flow 20% more fuel than the stock LTG injectors. That additional fuel flow allows for a significant increase in horsepower, with proper tuning. We estimate that these injectors will flow enough fuel to make up to 700 wheel horsepower*!
Take help you take full advantage of your new Nostrum injectors, we recommend pairing them with our Standard Bore Plus HPFP, which flows 37% more fuel than the stock pump. With a higher max operating pressure than our regular standard bore pump, and having a lower cost than the Big Bore pump, the Standard Bore Plus unlocks even more horsepower potential, and allows you to take full advantage of our high flow injectors! This is perfect for anyone who is looking to get the most out of their stock turbo, or run pump E85! That additional fuel flow allows for significant torque increases earlier in the rev range, and provide the injectors with all the fuel they need to make more peak horsepower, when properly tuned. Buying the Stage 1 bundle saves you money versus buying these parts individually!
Looking to make more power and hurt some V8 owners feelings? You’re going to want the Big Bore HPFP!
Inside the box, you will find everything you need to get your new fuel system installed quickly, including all the hardware and accessories that you need, as well as detailed installation instructions. When you are ready to tune, we have tuning guides available for your dealer or tuner. Being that everything is installed like a factory part, there’s no need to worry about secondary injection controllers, filling meth tanks, clogged meth injectors, or any of the other complex solutions people use to squeeze more power out of these vehicles. Additionally, these injectors are operating with all the OEM ECU’s engine management system diagnostics and safety functions – resulting in a much happier and responsive system!
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.
Why is injector spray pattern 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 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.

Frequently ask question:
Q: Can I buy the original KDI injectors?
A: The P-KDI injectors for the LTG platform have been discontinued. Years of technological, asset, and engineering improvements have allowed us to release our next gen injector, the LTG Stage 1. The LTG Stage 1 injectors' OEM equivalent spray pattern, coupled with their low latency, makes them easier to tune and provides an increased flow rate while also improving combustion stability. Additionally, the new stage 1’s have a higher maximum operating pressure than the P-KDI’s which make them a better fit with the Big Bore pump.
Q: Some tuners won’t tune your products. Why?
A: Some tuners, especially those who "grew up" tuning PFI vehicles, aren't yet comfortable tuning for upgraded Direct Injectors. For that reason, we always recommend reaching out to one of our recommended tuners for upgrading your LTG. Additionally, some third parties have competitive products, such as supplemental PFI systems, that they prefer to tune, as opposed to a simpler fully integrated GDI solution.
Q: How does a higher operating pressure help me make more power?
A: An injector operating at 240 bar will move more fuel than the same injector operating at 180. More pressure means more fuel through the injector!
