Why is firing order important?

Firing order is the order in which the spark plugs ignite a cylinder starting from when cylinder one is at top dead center. You will notice that the number one is always the first number on these plates. From cylinder one, the cylinders are numbered across the engine. If cylinder one is on the rear right corner of the engine, then cylinder two is on the rear left corner, and cylinder three is on the right in front of cylinder one.

The firing order never follows this pattern though as it isn’t ideal for keeping the engine balanced. This is why the firing order can change from engine design to engine design. The firing order is important for a mechanic to know, but many enthusiasts also enjoy knowing it.
