AB Extremal cosmological black holes are analysed in the framework of the most generalsecond order scalar-tensor theory, the so-called Horndeski gravity. Such extremal black holes area particular case of Schwarzschild-De Sitter black holes that arises when the black hole horizonand the cosmological one coincide. Such metric is induced by a particular value of the effectivecosmological constant and is known as Nariai spacetime. The existence of this type of solutions isstudied when considering the Horndeski Lagrangian and its stability is analysed, where the so-calledanti-evaporation regime is studied. Contrary to other frameworks, the radius of the horizon remainsstable for some cases of the Horndeski Lagrangian when considering perturbations at linear order.
