Pat the wings dry with the paper towels.
Mix the kosher salt, black pepper, smoked paprika, onion powder, and garlic powder in a small bowl.
Coat the wings evenly with the spice mixture in a large bowl.
For crispier skin, place the wings on a wire rack over a baking sheet and refrigerate uncovered for 2 hours or overnight.
In a small saucepan, warm the honey, red pepper flakes, black pepper, and lemon juice over low heat until just pourable.
Remove from the heat and whisk in the cold butter cubes gradually until smooth and glossy.
Stir in the lemon zest and salt. Set aside.
Set up the grill for two-zone cooking at 375F.
Place the wings on the indirect heat side and cook for 25-30 minutes.
Flip the wings and cook another 15-20 minutes until they reach 165F internally.
Move the wings to direct heat and sear until crispy with charred spots, flipping frequently.
Continue cooking until internal temperature reaches 180-185F.
Transfer the hot wings to a large bowl and toss with the honey sauce until fully coated.
Serve immediately.
