Review on ZCBZZ Valve Stem Caps by Keith Bradley

These valve stems look great but they will alloy with your aluminum or even copper valve stems and replacement valve stems cost you a lot of money and/or TPMS sensors my son thought they did would look good on his car and his girlfriend's truck, he didn't know they would oxidize and fuse to the valve stems as I'm a mechanic and that happens all the time when they sell aluminum valve caps they have plastic inserts to prevent this.
