Bravex 8 Pack Straight Boot Ignition Coils 15% More Energy F-150 for Ford Lincoln Mercury V8 V10 4.6l 5.4l 6.8l Compatible with DG511 C1541 FD508-Upgrade (Red)

Had a couple faulty coils (check engine codes misfire cylinder #2 and #8). These worked perfectly. Also replaced the original 2 piece spark plugs with new updated motor craft spark plugs. Before replacing the plugs I ran 2 tanks of seafoam in about 15 gallons of gas per tank. Wamed up the engine first, removed the 4 old coils and sprayed pb blaster in the plug holes. Loosened the plugs 1 turn and let it soak for 15 minutes. With this method all 8 plugs were removed without breaking the plugs. With new plugs and coils there are no more misfires and the truck runs as it should.

I bought these not sure how well they would work but I have to say for what you get at half the cost is absolutely incredible. I installed them in a navigator with new motorcraft plugs and it's like It was when I 1'st bought the car. All the power has been restored and it's running so smooth I can't even tell it's running inside the car again. Great product I would recommend these to anyone doing services on there Ford/Lincoln

Okay so most of us here were wondering the same thing can I put these on my 5.4 l f150? The answer was yes you can in my situation I have a crew cab 2006 5.4 and I bought these this past Saturday and placed them on tonight. These brave coil packs mustered up the energy I needed to bring all 8 cylinders back from the grave. They came in a nice package and were in a plastic liner in a row. They feel heavy and well made to the touch. The price was great for this quality product. I will come back and edit this review if I have any problems.

i purchased these thinking it would be a good replacement part for my 2007 ford F-150 5.4L i was doing another spark plug replacement and decided at 180K it might be good to replace the working coils as an upgrade while i was in there. the parts came out of the package looking clean and well made. However, a few weeks after installation the vehicle began to skip under light load. i determined it was either bad coils or my torque converter. while driving i noticed the check engine light (MIL) flashing. which indicates an active misfire. I was able to narrow down my cylinder 3 coil was misfiring due to a bad coil..... (EDIT)...... i was initially upset that the return window was so low on the product itself however i was contacted by the Bravex company directly and was immediately shipped a replacement set with no prompting. i was contacted by their customer service Dept. via email and i was pleasantly surprised by the quality of service. they saw that i had a problem with their product and remedied it with a new full set free of shipping costs. i did have a problem with the component so i cant give it a perfect score but the customer service experience was so good that i bumped my review from 1-4 stars. if youre looking for replacement coils choose this company to work with. i will be buying from them again given the chance.

The other coil boots are fine but this one shows signs of arcing despite dielectric grease on installment. Otherwise no problems but would like this resolved so I can edit the review for the five stars the rest of the coil boots deserve 🙂👍

2006 Ford Explorer XLT 4.6 V8 with 150K miles. Had a misfire condition cylinder 8 for a while (code P08308). These coils fixed that issue, vehicle is running smoothly. These installed easily. Will see how long they last, and add to review if something changes. Very good result, for the price.

One of my factory coils went bad causing my truck to run poorly. I bought this set for just a bit more than what I would have paid at any of the big three auto parts places near my house. Now my mileage is up and my engine is purring like a kitten despite the 240,000 it’s traveled.

These have been far superior to the other ones I ordered not mentioning names. They are actually so good that they made some other things fail because they pushed my other components so hard. And I mean my injectors. As soon as I put these in they cried out not enough gas and I was forced to replace one of my injectors right away. Of course it was already bad I just didn't know because my other coil packs weren't pushing it hard enough. These are definitely top of the line definitely worth the money when you can buy all eight for the price of one.
