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 (Yellow)

UPDATE: had them in the truck for a few months now and I'm getting "P0300" random misfire multiple code. 3 of the coils are already malfunctioning. Just go with motorcraft coils.ordered these and was pretty skeptical as I ordered similar ones from another company for my last truck (9 yrs ago) and ended up replacing them right away with motorcrafts... these BRAVEX ones are awesome though. had them in for a week now and they're fantastic. messed up two of the connectors when removing the old ones so I had to splice new ones on, and even the replacement connectors match up great. the coils are working beautifully as of right now, will update in a few months!

I hope this helps some people that are looking at this product. After doing some research on coils for my 2006 f150 5.4. This product was the top pick for performance, longevity, and price wise, even compared to motorcraft brand. Size comparison to the originals were spot on. Very well built they fit like a glove without any modifications, the original coils I had a misfire on cylinder #3. After installation truck runs smooth as can be even with ac on to put a load on the engine. No codes thrown so far and ignition system is working smooth per diagnostic tool. So far so good if any problems occur over the next 1000 miles I will update my review. If you are skeptical of buying like I was at first due to low pricing, and lack of videos with the vehicle running with them installed. I would highly recommend these coils they work great.

Even after installing these new coils my vehicle still was missing and consuming high petrol. I now had to buy again and replace the coils. I spent double the amount now. The return window is closed they say but I feel it was too short time for the return window. We Need to be allocated more time for replacement.

These were a great replacement for my 06 F150 5.4L. I replaced my plugs with the new Motorcraft SP546. At 380,000 km it was time for new plugs and coils.The coils were a direct fit. No issues with the connectors or fitment. The truck was running much better after this.I definitely reccomend them.
