Whisk oil, pili pili sauce, garlic, ginger, and lime juice into a marinade.
Rub generously over the ribs, cover, and marinate at least 2 hours, or overnight for best flavor.
Bring ribs to room temperature before grilling.
Grill over medium heat, turning occasionally, 20–25 minutes until well charred outside and cooked through, moving to indirect heat if charring too quickly.
