Does a fuel injected engine have spark plugs?

Modern engines with smart gasoline direct injection need spark plugs perfectly geared to the specific requirements of each combustion chamber.

What is the difference between fuel injectors and spark plugs?

So these are the difference between Spark Plug and Fuel Injector, I hope you are able to understand the difference between these.

Difference Between the Spark Plug and Fuel Injector:

Spark Plug Fuel Injector
In term of price point, Spark Plug is available comparably less price then Fuel injector. The Fuel Injector is a costly component.
