If an engine has four cylinders and two spark plugs per cylinder, how many spark plugs are installed in total?

Explanation:
Each cylinder has two spark plugs, and the total is found by multiplying the number of cylinders by the plugs per cylinder. So with four cylinders and two plugs per cylinder, you install 8 spark plugs in total. The dual-plug arrangement adds redundancy and helps ensure reliable ignition, since both plugs can ignite the air-fuel mixture. If there were only one plug per cylinder, the total would be four; with more cylinders, the total scales similarly (e.g., six cylinders with two plugs each would be twelve).
