The SVX coils are dumb coils...the later WRX/STI onwards have built in ignitors. The STI coils are a viable COP option, whereas LS1 or Bosch (as I'm going) will require a lead.

I'd go the GDB STI (or EZ30) units for sure, can jump 5+ times further than stock SVX coils. What you can do is set them up for a lead like I've done with mine or you can drill out one side and mount them to the head. You can pick up a set for around $150 from Import Monster... and buy 2 extras individually.
Bosch ones tend to fail for to easily, had 3 fail over the years - one exploded.
