So how many plugs are in the box? The picture shows 2 plugs for 40.25, so if I want 4 plugs, I should buy quantity of 2, correct?

These plugs are sold individually

should you buy enough for all of you cylinders or just what you need to replace?

You should use all the same make and model plugs in each cylinder. Never mix and match makes or models.

How many does the package have?

They are each, so 1 spark plug. If the seller has damaged/open packaging units they are a great price! I got 4 and they were in perfect unused condition, cept for the boxes of course

Disculpa viene en juego de 4 bujías o solo una

Compre la cantidad requerida, ya que se vende en unidades de 1 pieza.
