Review on Denso DAC673 6003 Ignition Coil by Daniel Icyblue

They work great! We've softened the Triton 5.4 liter engine, thanks to him for that! Got a full x8 set to replace a horrible decision to buy really cheap red x8 coils. PLEASE, if you are buying reels, DO NOT buy those amazingly cheap red ones. or yellow or blue! I had to replace both of my catalytic converters because of them and they didn't have a piece of ferrite in the spring like quality coils do (at least for my engine). The red coils melted and the springs rusted but the engine code was never issued! Other damages cost me a lot of money. I would buy these Densos again, they work great, no more dropouts. Don't skimp on coils, this is very important. Also replaced the spark plugs, that's another story with the flimsy, welded belts that now come with them that drain, awful!
