This is correct. The 8/9 has what I guess you could call a half COP setup with 2 cylinders having coils and the other two having plug wires leading from the coil to the sparkplug. The two coils did seem to be lacking though, the Denso ones that people upgrade to (Spoolinup and SparkTech kits) are much stronger. that being said, I ran my stock plugs out to .027" gap on the stock coils/boots/wires with no misfires at 26psi on pump gas, I then switched to the Denso coils and ran Denso plugs out to .031" gap with again no issues or misfires.
