The formula targets carbon and varnish buildup that reduces combustion efficiency and impairs components such as injectors, turbochargers and diesel particulate filters (DPFs). Use it as a periodic deep clean every 5,000 miles or whenever you notice rough idling, sluggish throttle response or increased regeneration cycles.\u003c\/p\u003e\n\n\u003ch3\u003eHow does AR6400-D clean injectors and improve combustion?\u003c\/h3\u003e\n\u003cp\u003eAR6400-D contains concentrated detergents and deposit-dispersing agents engineered to dissolve carbon and varnish that clog injector tips and skew spray patterns. Restoring proper atomization improves air-fuel mixing and smoother combustion without the need for mechanical service in many cases.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRemoves deposits from injector nozzles and spray holes\u003c\/li\u003e\n  \u003cli\u003eRestores uniform spray for better combustion efficiency\u003c\/li\u003e\n  \u003cli\u003eReduces rough idling and improves throttle response\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this product help my turbocharger and acceleration?\u003c\/h3\u003e\n\u003cp\u003eBy removing combusted-fuel residues that accumulate in the intake and on turbo-related components, AR6400-D helps recover lost turbo responsiveness.
