If you're dealing with rough idle, misfires, or poor acceleration in your Ford or Lincoln with the 5.4L V8 engine, this 8-piece ignition coil and spark plug set is probably exactly what you need. This kit covers all eight cylinders and is compatible with 2004-2008 F-150s, 2005-2008 Expeditions, Super Duty trucks, Navigators, and Mark LTs with the 5.4L V8 engine. The coils are direct replacements for DG511, FD508, C1541 and several other OEM part numbers, and they come with iridium spark plugs that provide better wear resistance and more reliable cold starts. Installation is straightforward plug-and-play - no special tools or programming needed, just swap out the old components with these new ones. The improved spark energy helps restore lost power, improves fuel economy, and eliminates those annoying misfires that can make your truck run rough. Whether you're doing preventative maintenance at around 100,000 miles or troubleshooting specific drivability issues, replacing all eight coils and plugs at once ensures balanced performance across all cylinders. Much cheaper than taking it to the dealership, and you'll notice the difference in how smoothly your engine runs afterward. Just make sure your current coils have straight black boots (not angled) before ordering, and you're good to go.
