Poor quality
The bolts do not line up with the bolt holes on the valve cover so I can't even use them

Product review: 1AECI00140.
This is an ignition coil. Here's the original one from my vehicle and the new one from 1A Auto. This fit the Hemi V8 vehicles and you can see the original and the one from 1A Auto are exactly the same, has all the same connectors, and comes with the bolts installed. The only thing you have to add is just a little bit of dielectric grease and it will install just like the original.

Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks!
In this video, we're going to show you ignition coil replacement. This 2008 Dodge Ram has the hemi 5.78 engine in it and the procedure to do it is the same for pretty much any truck, although if you have a Hemi engine in some of the other platforms such as the Dodge Durango or the Dodge Challenger, the procedure could be different. You actually go up through the wheel well for some of the cylinders.
Items you need include new ignition coils from 1AAuto.com. 10 millimeter socket - actually you'll need various rackets and extensions to get into different places on different coils -, flat blade screwdriver, and dielectric or silicon grease.
Open up your hood, on each side of the engine there are four coils. You can see the front one here, and then they go back, and it's all the same procedure for each one. Those ones you just need to use a short socket and a wrench. To disconnect, there's a little tab on the backside.
Push them towards the coil a little bit, push the tab to disconnect. Then a 10 millimeter socket and ratchet will remove the bolts that hold the coils. The bolts actually have little retainers on them so they don't come all the way out. Once you get it loose, just move it around a little bit and pull them up and out.
To access the coils on the passenger side, we're just going to remove the intake hose and the top of the air box. There's four clips, just unclip them. Loosen this clamp here, flat blade screwdriver, and pull this hose off, pull this hose off, and then bring your intake box up and off. It gives you access. On this side you may want to have extensions to do this second one here. Again, push the connector towards the coil some and push the tab and release.
Here's the original coil from the vehicle, and the new coil from 1A Auto. You can see it's exactly the same. It's going to install just like the original.
If you want to use some dielectric or silicon based grease and just put a little bit right inside the tube that fits over the spark plug. Put the coil back in, you'll want to push down firmly and then start the bolts probably with your hand. Once it's tight, reconnect the lead, put your air box lid back in, connect this hose, push it over. Get it locked in right. Flip the tabs up and on. Then tighten up this clamp.
Thanks for tuning in. We hope this video helped you out. Next time you need parts for your car, please visit 1AAuto.com. Also check out our other helpful how-to and diagnosis videos.

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!
These heavy engines have eight ignition coils, and each coil does two spark plugs and there's two spark plugs in each cylinder. We're going to show you how to remove this ignition coil. This is probably the easiest one on the engine to do. The one on the driver side rear, actually two of the ones on the driver side rear are pretty difficult. But we're going to start with this one and just show you how it comes out, and then we'll give you some tips later on how to do the driver side rear.
We'll start with removing these two 10 millimeter screws. They are really easy to come out. As soon as you crack them loose, you can just spin them up by hand. Then up here you have just a clip that you can push down on and release from the coil. All right, if pushing it down with your thumb doesn't work, you can always go with the screwdriver and just kind of wiggle it up. There we go. With the two bolts out of the way and the connector loose, you can slide this right up and out, and you can see it has these two boots on it. These boots can actually come off as well. They may come off when you do the driver side rear because pulling this out with these boots attached is really, really difficult.
All right, we're now going to slide this right back in. You want to make sure your connector is facing up so you can plug your plug in. Technically removing this engine cover will make it a little easier on yourself. But it's not necessary for this specific coil. All right, the connector's plugged back in. Now we can put these two 10 millimeters right back in the holes. With them tightened by hand, you can go back with your socket and ratchet and just kind of snug them up. You don't need to go too crazy with this. Just making them snug is perfectly fine.
Now if you've ever had to do spark plugs or ignition coils on one of these engines, you know that the driver side rear two ignition coils and all four of those spark plugs are really difficult to access. We would love to show you how to do that, but getting the camera in there to see anything is really difficult. I'm just going to give you a few tips on what I've done in the past to get these things out. A few things you can use are a ratcheting 10 millimeter wrenches to get the coils.
You can reach back, and if you remove this engine cover you have a little bit more swaying room. So you can use a 10 millimeter wrench, if you have a ratcheting one, that one's even better. And then you can get the bolts out. The other thing you can use is quarter drive socket with a swivel on the end, and make sure it's a shallow socket and you should be able to reach in and you can get some of these hard to reach 10 millimeter bolts.
Then once you do get those two 10 millimeters out of each coil, and you remove the plug on the top. You can just bend the coil out of the way because the boots are flexible. The only thing you have to watch out for is when the boot comes off there's a little tiny metal pin inside the boot and that's going to fall and you might lose it. So you have to be prepared to have that little pin pop out of the boot if you are going to remove the boots with the coil being separate. Those are a couple of my tips. It's definitely a challenge to do and it'll take a while, but hopefully that'll help you out and get you fixed up right.

The bolts do not line up with the bolt holes on the valve cover so I can't even use them
perfect fit and performance
This is the 2nd vehicle I've added these coils to. My F-150 at 100,000 got a set this summer. And now, my 2014 Jeep Grand Cherokee with a 5.7L HEMI got a fresh set. Easy install on this engine. I feel a little better pep in the acceleration. Overall, I like the look of the red Coil box as well in the engine bay.
Complete garbage. Caused random misfires from day 1!
As always a good trusted product. When it comes to certain parts I always buy from 1A Auto. I see them as the autozone of the internet. I've purchased front end conponents, coil packs, and other items especially if their are kit sets. I've had these coil packs before with my 04 ram 1500 5.7 hemi, and they were perfect and exceeded oem specs. I purchased this set for my 18 ram 2500 with hemi 6.4 and as usual was not disappointed, especially since these are lifetime warranty. As I said the autozone of the internet. I am very picky of what and where my parts comes from. I work on vehicles as a side gig and have used 1A for those jobs as well. If I won't put or use in my own vehicles, I won't put in others. 1A is my other trusted parts store.
Installing them took all day because it was my first time, but once they were installed, they looked terrific, and the car may have gained some power. It feels more awake now.
Good all around experience parts came fast.
I just upgraded my 2009 Dodge Challenger srt8 (6 speed manual trans) with these and iridium plugs all from 1a Auto. My vehicle has only 41,000 miles it's always maintenance properly, now after putting these new parts on (plugs I gapped per OEM Specs .050) I took it out for a cruise approximately 35 miles, it stalled out on me 7 times!!! Is there something additional I need to do? Please inform me, otherwise I will say this is a HORRIBLE PRODUCT , and not advise ANYONE to purchase these.
Great product
Looks amazing! Notice better mileage and doesn't lag anymore on my throttle response
