Fuel upgrades for the B58 Gen 1 are finally here! Our Stage 1 injectors flow 35% more fuel than the stock B58 Gen 1 injectors, allowing for a significant increase in horsepower with proper tuning. We estimate that these injectors will flow enough fuel to make more than 750 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, theres 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 ECUs 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.
