This kit brings three targeted treatments to the vehicle: a concentrated fuel additive to work through the fuel system and combustion chamber, a foam spray that cleans the converter and exhaust internals directly, and an engine flush that eliminates oil-borne varnish and sludge that can worsen emissions and performance.\u003c\/p\u003e\n\n\u003ch3\u003eHow will the three-step approach address a P0420 or P0430 code?\u003c\/h3\u003e\n\u003cp\u003eEach component targets a different source of reduced catalyst efficiency: fuel and combustion deposits, converter and pipe buildup, and internal engine contamination that affects combustion quality.
