These valve stem caps should be priced at -93.94 which is the cost of replacing four valve stems and TPMS sensors. Also, I wasted over two hours waiting for the stems to be changed. Covers corroded the valve stem and "welded" to the stem. They could not be removed even with penetrating oil. These caps had to be machined to prevent contact between the aluminum and the brass of the shank end. As you can see, I don't want to buy anything from Godeson anymore.
