Edelbrock Universal Performer EFI Nitrous Kit #71000 is the best way to get a major power increase in your fuel injected late-model street machine. This system works with your stock ECU for a simple installation. Performer EFI "Wet" Nitrous Systems supply nitrous directly into the intake stream, and the extra fuel is supplied through the OE injectors by raising the fuel pressure or changing the duty cycle. This is a single-stage system that is capable of an 50-70 horsepower increase. Fits any 4, 6 and 8 cylinder engine with return style fuel system.
