MSD82438 Ignition Coils, Blaster Series, Red, 8-Pack

I was a little nervous getting these as everyone says you should buy OEM coils, but at the price difference I decided to give it a chance. These have worked perfectly and I've put about 12000 clicks on my 09 F-150 now and they do perform well. The boot on these was a little shorter then the OEM ones I was taking out, but they fit snugly and I used a lot of diaelectric grease on them to make sure no water or anything every gets in there. In hind sight I should have just changed these when I did my plugs a while ago instead of waiting for my gas mileage and performance to drop. From now one when I do my plugs next time I am just going to swap these out along with them. I would highly recommend these to anyone looking to change out their coils.***********UPDATED REVIEWJust as a note I wanted to let people know how these coils are holding up 2.5 years later. These are still running so well, I am so happy with my purchase. I have driven about 140,000 km on these and they have given me no problems at all. I live in Calgary Canada, and my truck has seen -40C and it starts and runs with no problems. I drive not crazy hard, but its a pickup and I use it like a pickup, towing things and hauling heaving stuff. These coils have performed amazingly and I would totally buy them again. In fact I am looking at replacing some coils on a 2009 4.6L Explorer and it takes these coils which I am purchasing and installing without hesitation!************

I'm a gear head and have used MSD for years. With these the Boots are a little shorter than stock brown boots on my 09 5.4L 3 valve but fit and work perfectly. Very noticeable improvement in throttle response and pick up. Doubt there's any HP gain but considerably better response and pick up. Seems to run a little smoother at interstate speeds as well. I had a little bit of a shudder at highway speeds which is why I changed them and plugs at 86,200 miles.

Have had them installed on my Ford Expedition for over a year now (approx 10k miles). No issues whatsoever. Last set I used (not MSD) lasted maybe six months before one coil died. I don't know if it effected my mileage directly because I installed these when I did my cam phaser lock out so my mileage went from 18/19 to about 16/17 on the interstate. The decrease could be due to a lot of reasons...I'm mostly going to say it was because of the lock out and NOT the coil packs.

I purchased item. Opened box to find dirt and grease on several coils and some were bent. All coils appear to have been used.

I have a sport trac 2008 v8 4.6 3v this engine have the coil whit the long boot, one time on the road i have a coil fail and the only coil i have in my hand is the dy511 motorcraft short coil whel no problems since 1 month ago the check engine come on whit missfire code i decide go for this kit for me perfect fit no notice incrase power but the engine is runing perfect like new.

fit my 04 5.4 3v engine perfectly! 15k miles now and no issues. much cheaper than oem. been buying msd products for racing. cant go wrong here

If putting in a 2004 F-150 5.4 like mine.Been in for about 3 weeks. Sounds much smoother and mileage seems better around town, have not had a chance to check highway mileage yet since I was pulling an enclosed trailer. 11 mpg with that.

I love MSD products. Always great quality. These were super easy to put on. I changed my spark plugs and added these coils at the same time. Love the red bodies on them. These could be changed out in minutes. Car runs much nicer now.

The coils got rid of my rough idle and engine stumbling under load. I have a cold air intake, catback exhaust and programer in my truck. The best it has ever run; more power and better gas mileage. Highly recommend this product!

Es una mejora rápida y fácil de hacerle uno mismo con algunos conocimientos básicos de mecánica a la camioneta, en mi caso es una Expedition 5.4L y he notado una ligera mejora en el rendimiento de combustible, y una gran diferencia en la estabilidad del motor en marcha mínima y en aceleración ligera, se siente más "ligera" la camioneta Y además se ve super bien la bahía del motor con sus bobinas rojas.Incluye dos stickers grandes de MSD y un sticker metálico para poner en el cofre donde dice que es compatible con las regulaciones de emisiones de USA.Buena compra y buen precio (menos de la mitad de lo que costarían todas las OEM

exactly what I expected very happy with the coils
