Preheat the oven to 375°F (190 degrees C).

Combine the olive oil, garlic, chili powder, garlic powder, salt and pepper in a large re sealable bag; seal and shake to combine. Add the chicken wings; reveal and shake to coat. Arrange the chicken on a baking sheet.

Cook the wings in the preheated oven 1 hour, or until crisp and cooked through.
