ASNU have over 30 years of experience with injectors from all the various injector manufacturers worldwide. ASNU is represented in over 38 different countries, with thousands of injectors being tested and serviced in Aftermarket and Motorsport worldwide; a programme and experience unrivalled by anyone else in the world. This gave ASNU the greatest experience and understanding to develop a range of performance injectors that will do exactly what they are designed for -  Correct Performance. ASNU Performance Injectors are purpose-designed and built with the ideal spray pattern to match the flow required. They are designed to meet the varied demands of the Racing & Performance markets, with the largest range in the world!

All ASNU Performance Injectors have a multi-hole orifice cap, cut using the latest laser technology for greater accuracy and repeatability. Using this technology allows us to produce injectors with specific spray patterns and flow rates to meet the customers' exact requirements. The seven-hole orifice cap that we use in most of our injectors in the lower end of the range (300-1000cc) offer an ideal combination of Fuel Flow, Fuel Distribution and Fuel Atomisation. The seven holes produce smaller fuel droplets that will burn more efficiently, giving more performance and more laps for less fuel. This is a critical factor and should be considered when comparing ASNU injectors to any other Performance injectors.
