Stir together chili powder, salt, smoked paprika, garlic powder, onion powder, dried oregano, black pepper, and crushed red pepper in a small bowl until evenly combined.
Place pork on a cutting board and coat with olive oil; rub spice mix over the entire tenderloin until evenly coated.
Lightly coat air fryer basket with cooking spray. Place tenderloin in basket at a diagonal angle so tenderloin lays flat and straight in basket.
Cook at 400 degrees F (200 degrees C) for 5 minutes. Reduce temperature to 325 degrees F (165 degrees C) and continue to cook, until an instant-read thermometer inserted into the center should read at least 140 degrees F (60 degrees C), 12 to 15 minutes.
Remove from basket and let stand until internal temperature reaches 145 degrees F (63 degrees C), about 5 minutes.
Cut into ¾-inch slices and place on a serving platter. Drizzle with honey and serve immediately.
