05 Mazda rx8 firing order

Answer 1

I have listed the coils in order from the front of the car to back in the stock coil location.

Coil input colors can confirm this.

1) Green coil input wire is Leading plug front rotor (bottom-front spark plug)

2) White coil input wire is trailing plug front rotor (top-front spark plug)

3) Yellow coil input wire is Leading plug rear rotor (bottom-rear spark plug)

4) Blue coil input wire is trailing plug rear rotor (top-rear spark plug)

Hope this helps.
