They’re finally here! The long awaited Stage 3 injectors for the N55 & S55 are now available! Flowing a ridiculous 85% more fuel than the stock injector while still maintaining a 250bar operating pressure rating, the Stage 3’s are what you want when you have a 4 digit horsepower goal in mind. Developed to have an OEM equivalent spray pattern, the Stage 3’s deliver unparalleled performance without sacrificing idle quality or drivability.
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 that remove layers of protection and safety from your engine. Our injectors operate with all the OEM ECU’s engine management system diagnostics and safety functions – resulting in a much happier and responsive system!
Inside the box, you will find everything you need to get your new injectors installed quickly, including pre-installed decoupling rings and detailed instructions for a no nonsense install. When you are ready to tune, we can get you set up with one of our trusted certified tuners, or we have injector tuning data available for your existing dealer or tuner.
Take your Nostrum Stage 3 injectors to the limit by pairing them with our S55 HPFP upgrade kit, flowing an incredible 36% more fuel than the stock pumps! 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.
