On April 4, 2021, Region 10 entered into an administrative Consent Agreement and Final Order with
Adrenaline Performance LLC (Adrenaline) for violations of Title II of the Clean Air Act. Between
January 2017 and June 2019, Premier sold at least 671 parts or component that defeat or remove
required emission controls on automobiles, including heavy-duty diesel vehicles and tampered with the
emission control systems of at least 248 vehicles. The $48,600 penalty was reduced due to
Adrenaline's inability to pay a larger civil penalty. This settlement is part of EPAs National
Compliance Initiative for Stopping Aftermarket Parts Defeat Devices for Vehicles and Engines.
