Spring of 2021! I installed the Exile Autoworx Mazda KL wire cover for the front valve cover. Nice aluminum cover! They do work with Nology spark plug wire set. With the extra thickness of the wires I went with the spaced off instead of flush mounting it. I spray painted it to match my the color of most of my car with the Duplicolors Perfect Match BHA0959 Bordeaux Red (R78P) .
