what do you mean? they fit?
You need a standalone to run the LS1 coils, but if you buy Haltech's "dual coil" it's easy. Mount the coil to the firewall. Take your three stock wires (+, -, trigger) and wire them up. Buy an MSD wire kit and make plug wires. Done and done.
The stock coils are really good though. Why would you want to change them? Bump your dwell time up and they're good for insane amounts of boost.
Are the Nology wires any good? I know MSP people have issues running properly with them, but NA engines seems to do fine.
Gonna order what..The Nology's?*nervous* gonna order these from PG. ANyone else have trouble with em?
