i have a 2014 tundra with the 5.7 Flex motor and it has 105,000 miles. The truck has been trouble free and other than oil changes and new brakes at 1000,000 nothing else has been done. Does anyone know at what mileage do spark plugs need to be changed?

Pull one plug,
White= lean
Light Brown= just right
Black= too rich
worn electrode= replace.
