What is the firing order?

The firing order is the sequence of engine cylinders in which spark plugs ignite the mixture of air and fuel. The firing order for a particular engine is typically found in the owner’s manual. This firing order is designed to ensure that the engine’s cylinders fire evenly and produce power smoothly. An engine with an odd number of cylinders typically has a “1-3-5-7-2-4-6” firing order, while an engine with an even number of cylinders will have a “1-2-3-4-5-6” firing order.
