By treating the entire fuel line from tank to tailpipe, it aims to recover lost performance and improve combustion stability without removing parts. The product is supplied as a convenient pour-in treatment, sold here as a two-pack for repeated maintenance or multi-vehicle use.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cleaner affect catalytic converter performance?\u003c\/h3\u003e\n\u003cp\u003eThe formula targets carbon and contaminant buildup that can clog catalyst substrates and restrict exhaust flow.
