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 is a 2003 Honda Civic. It has a 1.7-liter, and this is similar procedure for Hondas and Acuras with the 1.7-liter as well as the 3.5-liter. Items you'll need include new ignition coils from 1AAuto.com, flat blade screwdriver, 10mm socket and ratchet, also a 10mm wrench will work.
Open the hood and pull the lever right here. Underneath there's a safety latch. Lift it up. Pick up and put the prop rod in place. Your ignition coils are located right on the top of the engine here: one, two, three, and four. Flat blade screwdriver to remove the cover. 10mm socket or a wrench would work as well to remove the nut that holds the coil in place. Take out the tab on the harness connection, press down and pull, disconnect, pull it up and out. We'll do the same thing for the other three.
Here you can see the old parts from the vehicle. New coils from 1A Auto, they're exactly the same, connector is the same, has the seal too. We're going to install and function just like the originals. To install, push them down in, you want to just put the connector on them. Down, push hard, 10mm nuts back on. Tighten. Don't want to go too tight. Get your cover and you're all set.
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 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.
Thanks for watching. Visit us at 1AAuto.com for quality auto parts, fast and free shipping, and the best customer service in the industry.

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.

After replacing my ignition coil my misfire problem became much worse. After changing out all the coils the problem still existed, turns out 1A auto sent me a bad part. Replaced the new coil with one of the originals and the car runs smooth now.
Called to get a refund but they said electronic parts arent refundable.
Thanks for nothing!
Awesome product
