These injectors originally have a flow rate of 61.8 l/h @ a pressure of 100bar, however, once Big Bang Injection is done with them, you will see an increase of 43% when compared to stock (nozzle flow rate of 88.2 L/H/100BAR). These injectors utilize a 124° spray angle and are capable of up to 850rwhp. Thanks to aftermarket tuners, injection quantity reduction is just a simple adjustment so you can decrease fuel quantity to satisfy the needs of your current setup, or crank it up 850RWHP to get your rig moving!
