Be veeeeery careful when looking to fit some of the fancy caps out there.
I bought a set to replace some chrome ones fitted to my wifes KA by the guys at Donnington Park when buying a set of alloys. They had fitted chromed valves and caps to match. Some scumbag had them away within hours of them being fitted!

I found out about some high-tech security versions from the US and bought 2 sets. Fitted one set and after an English Autumn/Winter couldn't get 2 of them off. Had to get "The Management" to drive to a tyre dealers to get new valves fitted on the others - you can imagine how that went down.

Tried silver spray painting standard plastic ones but have now given up and settled for the very underwhelming standard black plastic.
