has anyone had experience with the msd6 offroad ignition control and/or rev limiter? and nology hotwires and denso iridium plugs? if so, i'd like to know how they perform and if they're compatible with my 2002 xterra se-s/c. thanks!

my friend just put a new ignition and wires, if i were you, go with excel, they dont cost over 200 dollars, just a little over 50, and then buy the ignition controller, i hear good things, just be careful because i dont believe it is 'emissions legal' if you really care =\ but go with excel wires, they are cheaper and just as good, and go for the new ignition upgrade! tell me what you think
