Challenger Fuel System
Adding HEMI parts such as cold air intakes, exhaust systems, handheld tuners, or even a supercharger can increase your Challenger's horsepower, but increasing air flow without adding additional fuel can be dangerous. Prevent engine damage and detonation by raising your 5.7 or 6.1 HEMI engine's fuel pressure with an adjustable fuel pressure regulator or FPR.
