While those coils likely are OK, the OEM ones provide 80K volts, and never fail, so your MSD coils are at best a stock replacement, but more likely a down-grade. The E3 spark plugs are definitely a down-grade though. They are a gimmick, just like the "tornado" air tube insert. There is no advantage to that electrode design, in fact it slightly shrouds the spark from the air/fuel mixture, so they simply will not perform as well as a regular style plug. If you want to upgrade your plugs, get a set of Autolite or NGK iridium plugs. The taylor wires are likely overkill, but they are definitely better than the cheap parts store replacements, and if you want to upgrade your coils, put the stock ones back on.
