Review on 🔥 High Performance Ignition Coil DG508 8 Pack for Ford F-150 F150 F250 F-250 F-350 4.6L 5.4L V8 - DG508 DG457 DG472 DG491 - EXPEDITION MUSTANG CROWN VICTORIA LINCOLN MERCURY (Yellow) by John Duffield

Installed this complete kit on my well maintained 170,000 miles 04" Ford E250. Over the years I have replaced (3) but the others (5) were original and the van got a multiple misfire code.I installed new MotorCraft Platinum spark plugs 20,000 miles ago.After that I took it for a ride and got better throttle response,acceleration and (updated) fuel economy increased by 1.5mpg.As long as they've been around for a while work with no dropouts so for the price i say good to go and giving 4-5 stars i would advise including a small .33oz dielectric grease in the kit or use it elsewhere.
