what do you mean how old are the leads? buy new ford ones for about
£20

i mean the ford ht leads were designed 20 years ago what you saying thay gonna be better than say magnecor?? the ford leads dont provide proper & permanent RFI & EMI suppression to avoid interference to electronic management systems, ice etc also the std leads cant cope with high temps like these NEW UP TO DATE DESIGNED SILICONE RUBBER HT LEADS just my thoughts, you get what you pay.
