Or try my store here:

Jeg'* sells GTP MSD wires a little cheaper than Summit. Either way they sell the same thing. Jegs or Summit will do you nicely.

is the performance that noticable for plugs, and wires?

No. You might feel a slight increase in mid-high range rpms, but for the most part it'* a tuneup item. The hotter spark of the MSD coils might be good for 5hp, but only if you have quality wires to the plugs. (Taylor Spiro-pro or MSD superconductors)

You're gaining back what you lost with worn out stuff.

I'm still not a coil gets you HP believer yet. I think if your stockers are worn out then yes it'* like old wires.
