BDFHYK 8PCS Platinum Spark Plug Compatible with Ford Expedition F150 F250 F350 F450,Lincoln Mark LT Navigator,5.4L 6.8L V8 V10 Engine Replacement for SP515 SP546

Almost a year later, 10k miles and still going strong. Im impressed at what a bargain these were.

fuel efficiency and valor for money whit durability excellent

Installed in my 2006 Ford F150. Vehicle was feeling sluggish so I replaced the plugs and coil packs. I was a little hesitant because they're made in China, but the truck feels better and more powerful. Hope they last.

These seem great. Fit perfectly, went in with ease, seemed to be a strong match to the original in generic form. Have had them in for about a month and so far so good. Replacing the spark plugs on my 2004 F150 was tedious but not overly difficult if you are prepared. If you are replacing the plugs, you MUST get the Lisle 65700 Broken Plug Remover Kit for Ford 3V Engines. You will break the plugs and you will need it. It will happen and there is no other way to remove the broken plugs. It does work flawlessly if you follow the instructions. Also, if you can, make a raised platform around the truck and your life will be 10 times easier. I just used some long plank wood benches on either side about 18" off the ground, with a plank across the front of the truck. Unless you are 7.5 feet tall you will have to use a platform or crawl on top of the engine somehow, or use an over creeper to lie on which you will then have to reposition a thousand times.

i think they will work fine. I am changing today. However the socket i purchased on amazon did not work. would not go down over plug far enough to remove it. stan
