Catalytic Converter For 2013-2019 Nissan pathfinder 3.5L w/ Flex Y pipe

Usually the carrier of the three-way catalytic converter is made of porous ceramic material, and its ventilation holes are designed in the form of mesh and polygonal sections. However, its carrier does not participate in catalysis. The materials mainly used to catalyze exhaust gases are precious metal materials such as platinum, rhodium, and palladium covered on the carrier. Under the action of high temperature, the exhaust gases emitted by engine combustion are catalyzed and the harmful gases are removed. Transformed into harmless substances through oxidation and reduction.
