It's generally advisable to replace all of the spark plugs at the same time since they will most likely have the same amount of wear. This also helps ensure that all of the spark plugs are firing as they should together, which can help improve engine performance considerably.

Currently iridium spark plugs are the most expensive on the market as they're made of rare earth metal. Iridium plugs typically last longer, have a higher melting point, and create a more powerful spark. This means they help your car’s engine run better, and they last longer.
