The ignition coil pack is a crucial part of your ignition system. It's function is to convert the 12 volt power of your vehicle's electrical system in to 35,000 or more volts. This produces a high intensity spark at the spark plug which then ignites the fuel in the cylinder. Coils in general will wear out over time.

Hi. I'm Mike from 1AAuto. We've been selling auto parts for over 30 years!
To replace the ignition coils, you've got four because this is a four cylinder engine. They are all situated right here on top of the engine. To do one of these, it will be identical for the other three.
I’m going to start by unplugging it, so you push the lock in, pull this out. You might have to take two hands and just pull it off. Put that aside. Take a 10 mm socket and ratchet. Loosen the nut that's holding this on. Be careful not to drop them, because they are very small and they're painted black so they're hard to see. Luckily, this one fell on top of the alternator, so we're good.
Now I'm just going to reach under here and work the coil out. I have to break the little seal that's in there. That's your coil.
Here's our original coil and our brand new one from 1AAuto.com. Same style connectors. Same style boots with rubber seals. Same size and same mounting hole. This should fit in the vehicle and work great for you. Since this coil was working just fine, we're going to reinstall it.
Push it right into the opening. Line it up with that stud that's there. I'll just push it right down. I'll slide over the electrode of the spark plug, and then I'll reinstall the nut that's holding it on. Plug it in. These are just 8.7 foot-pounds, so like 9 foot-pounds, which is really just hand tight. Just give them a little snug like that and it's all set.

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 show you how to remove and reinstall the coil. Actually in these vehicles, the 1.4 and 1.6 liter, there's a coil per cylinder. It's recommended to replace these every 100,000 miles. For this, it's pretty easy. All you need is a flat blade screwdriver and a 10 mm wrench or a socket with a ratchet.
Replace the coils. You probably should do it every 100,000 miles. It looks like, actually, this car has been done pretty recently. It's pretty clean. It's pretty straightforward. There are a couple of little locks up here and this piece comes off. There's a harness here. Use your screwdriver and push on the tab up closer to the top and the harness disconnects from each one. Then, you need a 10 mm wrench or socket and ratchet to undo the nut. Pull firmly on the coil, and it comes up out.
Like I said, this looks fairly new. Put it down in. If you want, you can actually connect your harness first. Push the coil down on, put your nut back on and then tighten it up firmly. Like I said, probably every 100,000 miles replace all four. Put this back down and then you go, and they turn 90 degrees to lock in place.
