Most spark plugs including iridium spark plugs should have the gap already set to specs for your vehicle.

However I've found that some spark plugs weren't set correctly for the gap that the vehicle specified so I had to change a few spark plugs to the proper gap.

Take a spark plug gap checker and check the gap and see if it's correct for your vehicle.

Your vehicle should list the gap setting under the hood in the front of the vehicle.

If not check online or post a question on here with your vehicles make and model and engine and we can tell you what gap your spark plugs need set at.
