Heat your grill to medium to medium-high heat, and brush with oil.
Place the prepared wings in a large bowl. Sprinkle with salt, paprika, pepper, and garlic powder.
Toss until the wings are well coated in the seasoning. Let the wings rest while you prepare the sauce.
Place a medium saucepan over medium heat. Add the peach preserves and sweet chili sauce to the pan. Whisk to combine. Bring the sauce to a simmer, whisking occasionally. Cook until the preserves have melted, about 3-5 minutes.
Pour 1/2 of the sauce over the wings and use a large spoon to coat the wings in the sauce.
Use tongs to place the wings on the hot grill. Cook for 4 to 5 minutes, basting the wings as they cook. Flip the wings over and cook for another 3 to 4 minutes, basting the wings.
Use tongs to remove wings from the grill. Serve immediately.
