Fuel system upgrades for the Gen 1 B58 are finally here! Our Stage 2 injectors are for those looking to push their Gen 1 B58 to the next level, without having to rely on secondary fueling. With 66% more fuel flow than the stock B58 Gen 1 injectors, the Stage 2’s will allow for a significant increase in horsepower, with proper tuning. We estimate that these injectors will flow enough fuel to make nearly 900 wheel horsepower

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!

Bundle up and save! These great injectors are also available as part of our Stage 2 bundle which includes our Big Bore HPFP!
