Introducing Nostrum Stage 2 N55/S55 Injectors! Our Stage 2 injectors flow an incredible 55% more fuel than the stock S55 injectors, and 12% more fuel than the EU5 M5 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 over 900 wheel horsepower, and have already fueled more than 700 wheel horsepower vehicles - without the need for secondary port or meth injection!
