Ultra Insulation Blanket For Exhaust Catalytic Converter Durability Insulation Cotton Thermal Protection: Shields engine parts from extreme temperatures, reducing wear and preventing damage to nearby components. High-Temperature Tolerance: Built to withstand extreme heat, ensuring reliable performance even under continuous use. The honeycomb design achieves maximum flow rate and surface area, allowing catalytic reactions to fully engage with exhaust gas without reducing exhaust flow velocity. With its honeycomb structure, peak flow rate and surface area are realized, enabling full contact between catalytic actions and exhaust gases while preserving exhaust flow speed., Manufacturer: XKBUAPM
