If you have a stock OEM-style coil pack it should be marked 1,2,3,4.

There actually is two coils. One is for cylinders 1 & 4. The other is for 2&3. If you are standing at the front of the car looking at the coil pack, cylinder 1 goes on the top left plug (should say 1). Then the one below it is for Cylinder #2. The one to the right of that one in the bottom right corner is for Cylinder #3. Then the one above it is Cylinder #4. And going from the timing belt side to the drivers (trans) side it is Cylinder #1, #2, #3, #4.


The firing order I believe is 1, 3, 4, 2. Someone else can verify though.
