I have OEM MotorCraft spark plug wires and the Screamin' Demon Coil Pack seems to have fried them or the spark plug connections are no good. The spark plug boots just dont seem to snap on good. I need a recommendation for spark plug wires that can withstand the Screamin' Demon coil pack and have good quality connections in the boots. I found some Taylor wires on summit racing but they have two different boot angle options.

 

go with the taylor`s

best in the market period

 

STI's just put them in with denso iridiums, good improvement.

 

I just installed a set of Taylor ThunderVolt wires. Nice, good quality. Look for a set with the lowest ohm's per foot...

 

What boot angle did you go with?

 

you need the 135 degree boot

 

OK Thanks

 

They sell matching wires to go with the coil, I have them on my truck and they're pretty nice. They're called Livewires.

I would go with the matching Davis livewires for your 4.0L. My SOHC 4.0L uses 180 degree, not sure about the OHV.
