Firing order
Firing order is setup like this with the stock coil
Rear of engine
6--------5
4--------3
2--------1
Front of Engine
Coil pack
4----2----6
1----5----3
If you're replacing the coil, you might as well go with the 86/7 setup for that, as they are easier to find, and not as expensive as the 84/5 packs. HTH
