A V-type engine typically has one spark plug per cylinder. Therefore:

• A V6 engine usually has 6 spark plugs, one for each of its six cylinders.
• A V8 engine usually has 8 spark plugs, one for each of its eight cylinders.

Some special or high-performance engines may have two spark plugs per cylinder (a twin spark system), which doubles the number of spark plugs. For example, some Mercedes-Benz V6 engines use twin spark plugs, resulting in 12 spark plugs in total

. In summary, the number of spark plugs in a V engine corresponds to the number of cylinders, with one spark plug per cylinder being the standard configuration. Twin spark setups are less common and usually found in specific high-performance or luxury models
