Review on Ford F150 F250 Explorer Set of 8 Ignition Coil Pack - Upgraded DG508 DG457 DG472 Compatible - 4.6L 5.4L V8 V10 - Black by Kevin Webb

I finally replaced my original ignition coil modules with this after 127,000 miles and so far so good. I have a 2004 Ford F150 XL V8 Triton engine. Buy some Di Electric Grease, 1 small bag at your local auto store and put a small amount where you connect the side of the spark plug. You won't hear a click when it connects, so just push it in as far as you can (the 7mm bolt secures your position anyway). Coil Module #4 is tricky, see the YouTube video on how to install it. Time will tell if this continues. But so far so good.
