Here's a breakdown:
* 1: The first cylinder to fire is the one at the front of the engine, on the driver's side (left).
* 5: Next, the cylinder at the back of the engine, on the passenger side (right), fires.
* 3: The cylinder directly behind the first cylinder fires.
* 6: The cylinder directly behind the second cylinder fires.
* 2: The cylinder in front of the third cylinder fires.
* 4: Finally, the cylinder in front of the fourth cylinder fires.
This firing order ensures smooth and even power delivery throughout the engine's operation.
