They are perfect for 2012 Nissan Versa 1.8. The gap should be 0.044 and it takes a few minutes for them to form a gap. You need a 14mm spark plug and not just a deep head to remove and replace. Also, you'll probably want to get an intake manifold. Pad while you're at it, since you're going to take it off anyway. Good traffic and the car runs smoother and increases mileage.
