These are sold individually. Same squirter is used in the front on each side and in the rear (for models with rear wiper).
Please note that these aftermarket squirters are not made with plastic that is as pliable as the originals. They are prone to breaking upon install unless you trim the sides down a little so they need to flex less. Once installed they will break if you try to pop them back out. We do not guarantee these against breAKAge. We do not believe there is a better product made so we offer these with this disclaimer.
