Season turkey wing pieces on all sides with seasoned salt, seafood seasoning, cayenne pepper, and garlic powder. Transfer into a resealable plastic bag; seal bag and marinate in the refrigerator for 4 hours to overnight.

Heat oil in a deep-fryer or large saucepan to 350 degrees F (175 degrees C).

Cook turkey wings in hot oil for 15 minutes; turn wings over and continue cooking until the meat is no longer pink at the bone, 10 to 15 minutes. An instant-read thermometer inserted near the bone should read 165 degrees F (74 degrees C).
