Hi. I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my 20 plus years experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1aauto.com. The right parts installed correctly. That's going to save you time and money. Thank you and enjoy the video.

In this video, we'll be showing you how to replace the spark plugs and plug wires on this Honda Accord V6. Process is similar for most Honda V6s. Tools you'll need are a five eighth inch spark plug socket, an extension and ratchet and maybe an extendable magnet.

Replacing spark plugs and wires on these Honda V6s is actually a pretty easy job but it's also kind of easy to mess up. Many times I've heard people say, "I took all the wires and plugs out and then I put it all back together but now my car doesn't run right." That's because you have to put everything back together correctly. The key is just do them one at a time. Take one wire off and one plug off, put the plug back in and put the wire back on. Very easy to work on like I said; all these six plugs are accessible.

On the rear, you can easily see, they're all very easy to get to. What you want to do is you pull the plug out over to here and then you give it a good twist. While you're twisting, pull it up and out. That's your plug wire. You'll need a five eights spark plug socket and an extension and put it right down in there and then just take the plug out. Once it gets easy to turn, it's usually a pretty good sign that your plug is all the way out and if you have a good socket you should be able to pull it up and out. My socket is a little worn out so my plug stayed down in there.

So a good tool to have around is a little extendable magnet which goes right down in and pulls the plug out. Actually, you can see somebody that did this before. It looks like they put a little bit of a paper towel around it to hold it into their socket probably. So you got the plug out and if you're replacing the wires at the same time or if separately. Now, you want to just take the whole wire off and, again, here at the distributor, twist and pull and then the wires on this car are actually fairly new so I'm not going to replace them, but you would not put your new wire on right in place because you have to make sure that you put each wire back on the same spot on the distributor. That's why you don't want to just take them all off and then try and put them back on, you just do them one at a time. Always route the back the way they were originally.

Before your installing your plugs, you want to check the gap and according to the sticker that's on the hood, right there, it tells you what kind of plugs to have and it also tells you what the gap is supposed to be. I'm sure you can't read it, maybe you can, but it says the gap is 1.1 millimeters which translates into .044 inches. I have a little gap tool and .044 just barely gets through there. That's set correctly. You might have noticed I've skipped through a different hole, but a good way to put these plugs back in is actually with a little bit of glue. Just put a little glue on there because my socket is worn and it won't hold on to the spark plug. A little bit of glue makes it so the spark plug sticks in there. You get it down in, start turning.

You always want to make sure you could turn it by hand first because if it's difficult to turn at all then you might be cross-threading is and you don't want to do that. Okay, tighten it. You want them snugged but not too tight. Put the spark plug wire down in there, make sure it clicks. Make sure you put the wire back into its correct spot.
