I currently have a 2005 F150 Lariat SuperCab with a 5.4 3v. Current mods include AFE intake, BBK 80mm Throttle Body, Super Chip Flash Paq, Magnaflow cats, 3 in y pipe back into a magnaflow and dumped before the axle. I have e-fans waiting to be installed. I am trying to squeeze what i can out of my engine on a tight budget. I have read mixed reviews about using COPs with higher voltage. Will changing to a higher voltage COP add more power? I have seen that there are some by MSD, Granetteli, Sultans of Spark. I saw this set in a offroad magazine for a decent price. http://www.performancedistributors.com/soscoils.htm
Any thoughts or info is greatly appreciated.

 

Don't waste your money. This isn't a 1960's points/condenser system with spark plug wires. There is very little (negligible) voltage loss with COP ignitions. You likely wouldn't gain anything at all from using them. 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 it.

Get a custom tuner/dyno if you want more power without going FI.

 

The cheap Ebay cops are as good as any.
