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.

Ignition Coil Set worked great. Took care of the problem. Would definitely order again from 1A Auto.

WOW! i felt a big difference as soon as i start my civic , more sharper and smoother and better response when i stepped at the gas pedal and i know i got better mileage from it thank you ?
Great parts that arrived quickly
Works Great
So far so good! I have them installed on my 2000 toyota sle 250 since last couple of weeks ago and still no knocking sound from the transny or any lack of power. Recommend to have these if you are looking for a better performance for your car!
Very good customer service support.
These parts will fit and function on your vehicle if it's the 2.4L engine.
This is not the correct part for your vehicle, but we do carry the one you need. The correct part number is: ICA33923.
I have a k24 4cycl so they should fit in a k20 4cycl
