Easy to Install and Increases HP by up to 12%

The 2012-2020 Charger SRT8 HEMI was on the Super Bee platform that would be renamed in 2015 as the Scat Pack. Additional styling changes were made to accessories and badges that gave additional nods to the 60s and 70s muscle car of the same name. The Charger SRT8 included a 6.4L engine rated at 470 hp as well as major upgrades to brakes and other systems. The dash came with launch features like 0-60 timing, G-Force readings, and ¼ and ⅛ mile drag timers. These launch features would come in handy when you increase your horsepower by up to 12% with our plug n’ play E85 conversion kits.
