Professional Racing Coil for Ford F150 F-150 Lincoln Mercury V8 V10 4.6L 5.4L 6.8L Compatible with DG511 C1541 FD508-8 PACK (15% More Energy)

Fixed my P0300 code on my 2006 Explorer 4.6L. VERY easy to install. Product looks of very high quality, specifically the boots (which as an FYI to any reader, the boots are one of the primary reasons a coil "fails." It's often not the coil itself, but rather a boot that has broken down and is arcing to a metal surface. Similar to when spark plug wires would break down.) Product also looks nice installed on the engine. Lastly, price was great. I really only wanted the yellow ones ($10 cheaper) however this red "racing" version was the only one available with next day shipping (needed to get the truck back up and running ASAP.) Not sure what's "racing" about it (marketing hype I'm sure) but nonetheless, they work flawlessly. Time will be the true test!

I don't normally review products here, but i'm so happy with the quality and performance of these coils. First of all, the set of 8 came in a very nice package, molded plastic (not like the ones I bought for my BMW, cheap knock offs that went out after a few days). So far I had these on my 06 F150 5.4L Triton for a week only, but I love them the first day I installed them. I noticed a dramatic improvement during drive and idle. I live in Midwest and so far I am putting these to the test driving in a freezing condition. I will give another feedback after about 3 months.You can see and feel the quality(nice color too) as soon as you open the box. Highly recommended!

2006 Lincoln Navigator 5.4L triton.Great price obviously. Fast shipping. Coils seem heavy and built. Time will tell how good they really are. For this money though, definatly worth a shot.

FYI -- 2004-2008 F-150 if you start getting a bucking sensation at around 50mph while going uphill that feels like your tranny is slipping, do a tune-up first with all new plugs and change the coils, too. I had the dealership change my plugs because of the notorious breaking plugs in this generation of the F-150 and the price of the tool to remove a broken plug was as much as the cost of the dealership labor. Unfortunately, the price quoted for changing the coil pack was astronomical. So, I had them do the tune-up and hoped for the best. I had asked for my old plugs so I could make my own assessment. I knew I would have to change the coils quickly. The old plugs (2) were in bad shape and I could feel the hesitation where the bucking used to be. I am 'old school' and 'if' it ain't broke don't fix it', so, of course, I waited for the misfire code three weeks later. I did say, I knew it would have to be done, right?I just installed these coils (<50 mi.on them) and they seem to have solved my misfire problem. I've given 5 stars because they're a perfect fit, cost a fraction of OEM parts and they work. In reading lesser reviews, I hope these coils continue to work flawlessly for at least a year. I saved my old coils as suggested, just in case. I'll update my review if anything changes. The price was my main reason for purchasing these because I was able to get all 8 for the price of 2 after market "performance" coils. I did notice a little more 'giddy-up in her go' on the highway but that was a short hop. I'll know more once I can put her through her paces in the spring. Winter in the Adirondacks isn't a good time to be fiddling with your engine. I hope this review helps. Thanks to all reviewers, information is knowledge. Keep the shiny side up and the rubber side down :-)

For the price of 1 OEM Motocraft ($89) ignition coil you can get this 8 pack PLUS the tools (Beer) to install them. Quick and easy to swap out on my 2010 f150 5.4l. Eliminated the hesitation under acceleration problem I was having. Not sure if it was these or the new spark plugs but my MPG went from 11.9 to 14.5/15. Can’t say if these are “racing” quality or performance enhancing but they do work well and solve a problem for cheap.

IF you need a cheaper option for replacing OEM, these will work. But not the best for longevity, OEM is better. i would not replace your OEM coils with these if it is not needed. Would not consider this an upgrade.

They started out good but one started misfiring after about 1200 miles. Replaced with a Motorcraft and runs fine. I could not find any warranty info.

Installed myself on 2006 F150 5.4L V8 with 125K miles. Took about 2 hours. Truck was misfiring between 40-50 MPH. These fixed it and now truck runs great. I did have the spark plugs changed out at about 90K miles so I knew the misfire wasn't from the plugs themselves.They came in a nice package and box on next day shipping and seem to be high quality. The whole pack of 8 coils was $70 and the local auto parts store wanted more than $200 for a pack of 8 coils.Only had them in for about a week but so far so good.
