WeaponX or ???
WeaponX has a pretty high failure rate. Global automotive on ebay and Motorcraft COPs are the most reliable. Buying "high performance" coils are a waste. This isn't a 1960's points/condenser system with spark plug wires. There is very little (negligible) voltage loss with COP ignitions. If you had forced induction, and were running up against spark blow-out from the swirling intake charge, then you might have to start looking at different COPs.
