In a small bowl, combine chili powder, smoked paprika, garlic powder, cayenne pepper, and salt. Mix well to create the spicy seasoning blend.

Pat the salmon fillets dry with paper towels. Brush both sides with olive oil, then generously coat with the spice mixture, pressing gently to help it adhere.

Preheat your air fryer to 400 degrees Fahrenheit for 3 minutes.

Place the seasoned salmon fillets in the air fryer basket in a single layer. Cook for 8-10 minutes until the salmon is cooked through and flakes easily with a fork.

While the salmon cooks, mix sour cream with lime juice in a small bowl. Set aside for drizzling.

Remove salmon from the air fryer and let it rest for 2 minutes. Use a fork to gently flake the salmon into bite-sized pieces.

Warm the tortillas and fill each with shredded cabbage, flaked spicy salmon, a drizzle of lime crema, and fresh cilantro. Serve immediately.
