Color-coordinate your engine bay and protect your wiring and hoses at the same time using this handy kit. The kit includes a total of 40 feet of split convoluted tubing, in four different sizes -- ten feet each of 1/4", 3/8", 1/2", and 3/4" inside diameter. That's more then enough for one car. The loom is pre-split for easy installation. Great addition to an engine bay already spruced up by colored silicone hoses. Heat and solvent resistant. Your choice of five colors.
