Preheat your air fryer to 400°F (200°C) to ensure a high-heat environment for maximum crispiness.
Use a paper towel to pat the chicken wings completely dry, which is the secret to getting that perfect golden-brown skin.
In a large bowl, toss the wings with avocado oil, garlic powder, onion powder, smoked paprika, sea salt, and black pepper until evenly coated.
Place the wings in the air fryer basket in a single layer, making sure they are not touching so the air can circulate freely.
Air fry for 18-20 minutes, flipping halfway through, until the skin is blistered and the internal temperature reaches 165°F.
While the wings cook, whisk together the sugar-free BBQ sauce and sriracha in a small bowl to create your spicy glaze.
Transfer the hot wings to a clean bowl, pour the spicy BBQ glaze over them, and toss thoroughly to coat every inch.
Serve immediately alongside the fresh celery and carrot sticks for a refreshing, high-volume crunch.
