It circulates through the fuel system and the exhaust path to target stubborn carbon deposits, phosphorus, and zinc contamination that can impair catalytic operation and sensor accuracy. The product is supplied as a convenient 16 fl oz solution and this listing is for a two-pack, offering two treatments for preventative maintenance or follow-up service.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this additive help when my vehicle feels sluggish?\u003c\/h3\u003e\n\u003cp\u003eThe formula works as a fuel system and exhaust cleaner to reduce deposit buildup that chokes airflow and fuel spray patterns.
