A Dodge Charger should roar, not wheeze, during hard acceleration. Clogged fuel injectors rob your Hemi or V6 of that signature muscle. Dirty injectors cause rough idles, misfires, and sluggish throttle response. We tested ten popular fuel injector cleaners on a 2017 Charger R/T 5.7L and a 2020 Charger GT 3.6L over several weeks of daily driving.
Some products did nothing noticeable at all. Others cleared up hesitation and smoothed out the idle within fifty miles. This list delivers the five best fuel injector cleaners for Dodge Charger owners who want real performance back. Each recommended formula contains high levels of PEA (polyether amine). That specific ingredient dissolves baked-on carbon deposits inside modern injectors without damaging seals or O-rings.
Pour the cleaner into a near-empty gas tank, then fill up with premium fuel. Drive at highway speeds for thirty minutes. Our top picks restored crisp throttle response, eliminated cold-start stumbles, and even improved fuel economy. Do not let dirty injectors turn your Charger into a sluggish sedan. These five cleaners bring back the muscle car experience you bought.
