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.

I bought a 2003Honda Odyssey about a year ago. It ran ok, but had 124k miles on it and I didn't know if the plugs were replaced recently or if they were on their way out, but I was getting an intermittent miss that seemed to be coming from a bad coil and decided to go ahead and replace the plugs and coils while I was in the mood.
I may be a dinosaur, but the price for this set when I bought it was pretty reasonable compared with buying separately from the local chains.
It's hard to judge the quality of spark plugs by looking at them, but I installed these and the new coils and it fired right up and has been running great for the past 2 weeks.
The bolts that secure the coils are not recessed into these like they were in the old coils, but they fit fine and are working fine so far.
Only time will tell how well everything holds up, but luckily this is a pretty easy job on my Odyssey.
I honestly don't expect to have to replace these again while I own the van.

So far so good. Had a couple of coil packs working intermittently on my Acura so decided to replace the entire set and spark plugs as well. Chose these based on price and other good reviews. Appear to be well constructed and exact duplicates of the original. Solved my misfire problem and got my car back on the road again. Would have given 5 stars but have only had these installed for a few weeks so can't speak for their longevity. But as I stated, so far so good and I would most likely buy TRQ again if ever needed.
