Automotive Ceramic Catalyst Thermal Insulation Cotton Gas System Ceramic Catalyst Thermal Insulation Material Heat insulation protection: prevent high-temperature exhaust gas from thermal damage to peripheral parts and prolong their service life. For example, reduce the impact of high temperatures on nearby sensors, wiring harnesses, etc., reducing their risk of aging and failure. Maintain the working temperature of the catalyst: it helps to keep the ceramic catalyst working within the appropriate temperature range and improve its catalytic efficiency. Ensure that under different working conditions, the catalyst can effectively convert harmful gases into harmless substances. Designed for gasoline engines, its efficient airflow boosts performance—your top choice for a reliable, long-lasting catalytic converter cleaner! High Efficiency:With its high-efficiency catalytic case, this converter optimizes exhaust gas velocity and improves emissions., Manufacturer: AWEDKKFI
