Catalytic Converter flex For 2007 – 2016 Nissan Altima Rear EPA high flow

As a downstream device in the engine, the life of the three-way catalytic converter will be directly affected by the working condition of the engine. When the engine is not working properly or is not properly maintained, it may be damaged. For example, a three-way catalytic converter needs to work effectively within a certain temperature range. Its optimal operating temperature is generally 400-800°C. When the temperature exceeds 1000°C, its precious metal coating will sinter and become necrotic due to the high temperature, and it will lose its working ability.
