What sets Nostrum apart: 

• 46% Larger than stock GTI injector 

• Direct Fit, no harness or spacers required  

• Ethanol Compatible  

• OEM equivalent spray pattern  

• Every injector is tested statically and dynamically to ensure best quality product and set batching  

• Includes comprehensive installation guide  

High flow fuel injectors for the Gen 1 & 2 EA888 are here!  Our Stage 1 injectors flow 46% more fuel than the stock MK6 GTI 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 nearly 600 wheel horsepower – without the need for secondary port or meth injection!   

Inside the box, you will find everything you need to get your new injectors installed quickly, including  detailed installation instructions. When you are ready to tune, we have injector tuning data 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!  

Take full advantage of your Nostrum Stage 1 injectors by bundling up! The Stage 1 EA888 bundle includes our Standard Bore high pressure fuel pump, flowing 36% more fuel than the stock pump! 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.  

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.

Frequently ask questions: 

• Q: Why don’t I see horsepower gains with just a pump? 

A: Fundamentally we have to look at the entire fueling system and “where” in the rpm range the limits are. DI fuel systems in stock trim are often pump limited at middle rpm (peak torque) and injector limited at high rpm (peak power). This is due to engine speed. HPFPs are mechanically driven pumps (driven by the camshaft pump lobe spinning at ½ crank speed) and are RPM (engine speed) dependent. Many of the quoted flow increases in the aftermarket are purely displacement based comparisons: where by example the big bore pump has a piston diameter X% larger than the “stock” pump or the swept displacement ((3.14*(radius)^2)*(stroke))of the pump Y% larger than the stock pump. The larger displacement of the pump really shines in low rpm, where the fuel injector has plenty of time (crank angle degrees) to inject fuel. As the engines starts to approach peak power the engine speed starts to become quite short and is limiting the injection duration (crank angle degrees) for the injection event (which is another reason why we like to increase fuel pressure up high!).  

• Q: Why do your numbers say I will make less horsepower on E85 than 93 octane? 

A: Great question! The numbers we list in the product descriptions are similar to the numbers a turbo charger lists for air flow. The numbers are the “fuel system capacity to generate power” regardless of the other engine system limitations (air handling, mechanical limitations, knock propensity). Essentially the numbers are calculated assuming “sufficiently large air flow”, “sufficiently capable mechanical assemblies” and disregarding knock limits. The equation uses actual observed engine volumetric efficiency (when available from sponsorship vehicles) and fuel capacity (including target pressures) to calculate power. Gasoline has more energy per mass volume than E85. So the higher fuel flow capacity will mathematically generate higher power potential for a gasoline than a high ethanol content fuel. The other variables (air flow, spark, rotating assembly strength, charge cooling, mechanical assembly strength) are highly variable from build to build. This is why we state horsepower capacity for the fuel system – representing the potential of the fuel system if you have all the other aspects of your build addressed!
