Because my car has an Real SPI, i must say this in the Picture is not an real SPI. My car has only one Fuel Injector and one throttle valve.

But this SPI in the Picture has two Injectors and 2 throttle valves...

Depends on who makes it, its still basically single point as it injects it all at the start of the intake manifold, its similar to ford's throttle body injection system the one we have.
