Some Help Please

[Yellow2001400ex]

Do they make a performance sparkplug and wire for my 400EX?
I've thought about putting a Bousch Platinum plug in if they made one to fit but i didn't know if there was a performance plug and wire kit i could get. Thanks for the help.

I could be wrong, but aren't platinum plugs made for longevity and not really high performance?

run a ngk plug. and they don't make wires for a quad
