So I may not have done my due diligence when I bought this, but you should be extremely careful. Aluminum often has a tendency to alloy with the metal on the tire shank due to rust or weather, and the only way to remove them is to cut off the shank and replace.
Aluminum on metal stems = corrosion and 4 new valve stems and pressure sensors. Cost me way more than all other stock caps even though they looked like a good deal. They could not be removed or cut off due to the level of corrosion due to being made from aluminum.
