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 replace an ignition coil on this 2003 Honda Odyssey. We'll just do one, but all six cylinders are basically the same procedure. The front side's very easy. Their backside is easy as well, but you just can't see things as well. You have to do it a little more by feel. The only tools you'll need are a 10 millimeter socket with a ratchet and extension, a flat blade screwdriver, and a T40 Torx driver, and Honda recommends you replace these coils at a hundred thousand miles.
I have a 10 millimeter socket, and I have an extension because one of these, anyways, goes down in there, but there are four bolts that hold the engine cover on here. Now you need a flat blade screwdriver, and there are basically two little clips. Turn them a quarter of a turn counter-clockwise. Now just make sure that they come out and there is another plug on the end here that you have to pull up just firmly and pull that out. Now I'm looking at it from the passenger's side and you can see the coils right down here: one, two, three. Then for the rears, there's actually there's no cover and you can see the tops of the coils. There's one here, two, and three. There's plenty of room to reach back in there and take them out.
First thing, each one has a harness and there's just a little tab that you press in and disconnect the harness. I'm just going to do one to show you. I'm using a T40 Torx bit and a socket, and there's plenty of room right in here. Just loosen this bolt up. I'm going to remove it, and then grab your coil, shake up and down a little bit, pull it all the way out.
Here's a new coil from 1A Auto. It's an exact replacement. Put it in, right down on. You'll feel some resistance, just push it down on firmly and put your screw in. Start it with your fingers; T40 bit back in and tighten on their firm, not too tight, though. Reconnect and repeat for the other cylinders.
Now you bring this down. You put your thumb on here. You can see that go right in, see these plugs go right in. Push it down on, push that into place. Okay, and turn these a quarter turn clockwise. Put the engine cover back in place. I'll spare you some of this. I'm just tightening up those bolts. I basically just put them in by hand first, make sure they're going in correctly. Then just tighten them up firm. You don't have to have them really that tight at all, and you should be all set.

Perfect Fit!!
I always really appreciate 1A Auto and TRQ installation videos because they are so professionally created and are extremely helpful. Admittedly I do not want to spend too much on a 22 year old vehicle, but even though you can find parts on Amazon for half the price of what 1A Auto charges, sometimes it is just not worth the hassle if the Amazon parts don't fit well (which was the case here) and you cannot beat the direct service, post-sales support, and in many cases lifetime warranty that 1A Auto provides (but then again, how much more life can I get out of a 22 year old vehicle, so I still need to balance all that vs. the additional cost that includes my time as well). In short, 1A Auto is the perfect one-stop, trouble-free parts and support shop for my vehicle!

Bad Coils, Great Company
Unfortunately, six months after installing these coils they started going bad. When the third one failed within a month of the others I decided to replace them all with Duralast. I cannot recommend these coils: 1 star. BUT, 1AAuto has been great through it all. I would definitely recommend them to anyone wanting to buy parts online. I will be buying from them again in the future. 5 stars for 1AAuto.
