Ceramic Coating: Our advanced ceramic coating option helps control heat soak. The piece is coated in a thermal barrier (available in black only) that looks great and protect wires and hoses from heat. Please note the coating may need some extra "curing" to prevent flaking after installation. Please allow the part to heat up during normal driving or idling and then completely cool before putting it through it's paces.
