In a large resealable container, combine the salt, sugar, pepper and water. Stir until the salt and sugar are well dissolved.
Add the wings. Cover and place in the fridge for 1-33 hours.
Set up your sous vide for 155 F.
Remove wings from brine. Shake off excess brine and transfer to a sealable bag. Vacuum seal making sure to remove all of the air.
Sous vide the wings for 3 hours.
Remove the wings from the sous vide bag and spread out on a sheet pan. Pan dry and transfer to the fridge overnight. This will let the skin dry to get crispier. If you are in a hurry you can skip this step.
Preheat your air fryer for 5 minutes at 350 F.
Toss wings in your favorite seasoning. Lightly spray your air fryer basket with non-stick spray. Add to the air fryer basket and cook for 6 minutes. Flip and cook 6 more minutes. If the wings need to be crisper at this point, turn the heat up to 400 F and cook another 3 minutes.
