Add chicken to gallon-size zip-top bag. Add Mojo Chipotle and seal bag; massage to coat chicken in marinade. Transfer chicken to refrigerator; marinate at least 4 hours, or up to 48 hours; drain chicken, discarding marinade.
Heat grill to medium-high heat. Add wings to hot, greased grill grates. Grill, flipping once, until charred and cooked through, about 15-20 minutes.
Transfer wings to serving platter; serve with celery and ranch dressing, if desired.
