New Injectors

Been thinking about changing my injectors. Is it worth using the merc injectors? Heard a couple of rumours about them before but not quite sure about the matter. Can anybody shine any light on the matter for me please. Thank You Rich  

Just bought a set myself.  Had a quick search through this and other forums and only found one negative report out of 5 or 6.  I think there is a slightly different spray pattern but they should last longer as they're brass.  Will update you when I get round to fitting them.
