FAQ RX-8 WS AEM Kit installation Help

Remove the positive and negative pole from the battery. Then remove the air filter box and suction hose.
Disassemble the old ignition coils, holder and ignition cable.
In order to get closer to the plug of the spark plugs, it makes sense to screw the left wheel down at the front.

Please always make sure that the firing order is correct!
Therefore mark the connectors with an edding when removing them.




Cable Scheme:

Leading is always the lower spark plug, trailing is always the upper spark plug.
Leading Front = L1, Trailing Front = T1, Leading Rear = L2, Trailing Rear = T2
OEM wiring harness 3 colors per connector:
L1 = Black/White, Green, Black
T1 = Black/White, White, Black
L2 = Black/White, Yellow/Green, Black
T2 = Black/White, Light Blue, Black


The scheme must be done exactly the same way for the AEM coils, otherwise the ignition cables are too short!

Mount the ignition coil holder with the 4 short spacer sleeves without coils with the 3 screws M6 wrench size 10 supplied
Always screw the earth plug (-) ENG either to the inner holder screw or to one of the ignition coil bolts from the holder and earth (-) BAT to the (-) battery pole.

First mount the AEM ignition coils for leading rear and leading front and make sure that you have the correct adapter and ignition cable assignment
Always spray a little WD40 or Ballistol into the ignition plug, then they will click in nicely.
Be sure to do the following carefully:
The gray silicone plug must sit flush on the coil head. No groove/gap should be visible on the round surface! See pictures.
If the plugs are not perfectly clean, coils and cables can be damaged.
IMPORTANT When operating the coils, the ignition cables and spark plugs must always be connected flush.
Otherwise they can be destroyed in seconds.




Insert lthe 4 long distance sleeves.
Then mount the AEM ignition coils for trailing rear and trailling front, as well as the 4 M6 hexagon nuts




Finally, if this has not happened before, connect the 62cm long ground cable (-) BAT to the negative pole screw connection of the battery and connect BAT (+) to the battery.
Then fix the cables with cable ties.






Reinstall the suction hose and air filter.
Before starting the engine for the first time with the new coils, Please ALWAYS
calibrate eccentric shaft sensor and delete N-VRam, see here:
