injectors mate . .

open the bonnet, and look behind the rocker cover, see if you have 1 green injector, or 4 . . .

1 is Spi - single point injector
4 is Mpi - multi point injector

single point injection is a very old way of fueling a engine and hardly ever used anymore mpi is the most common form of fuel injection 4 injectors one for each cylinder = more efficient, more power etc
