Review on 🚗 CarBole 8 Pack Curved Boot Ignition Coils - Black, Enhanced Energy for Ford F-150 F-250 F-350 4.6L 5.4L V8 DG508 DG457 DG472 DG491, Lincoln Mercury Crown Victoria Expedition Mustang - 15% More Power by Ted Higdem

I installed this about a week ago and have only done one long drive so far and wow the engine runs smooth and the throttle response has improved a lot . I've noticed an increase in typical fuel economy despite intentionally "banging" the transmission throughout the drive. I recommend that you take the time to blow the deposits out of the spark plug cavities with compressed air and replace the spark plugs if you even remotely need them while you're there. Take dielectric grease and apply it to the tips of the COP boot and to the o-rings on the outside of the COP boot to prevent water from entering the connector cavities, which is detrimental to all COPs. *After spending some time with these new aftermarket COPs I will post an update. So far, I am very satisfied.
