These are where your spark plugs are on this 2009 Chevy Suburban. It's the rearmost one of the driver's side. We have four in each side. One, two, three, four. We go over to the passenger's side. This one is a little bit trickier to get to. It's in the way, way back. We've got back there, one here, one here, and one here. It'll be just enough room to get it. We're going to show you how to replace one on the driver's side front. This procedure is going to be the same for all of them. It just might take a little more maneuvering to get to the other side.
I'm going to give this a little turn, and then you don't want to pull on the wire. All you've got to do is work it off of the electrode and of the spark plug. It's usually on there pretty tight. I should also mention that you should do this when the engine is cold because we're right next to the exhaust manifold. Just put this to the side. You should do these one at a time.
Spark plug is down here in the head. I'm just going to take some compressed air. Just blow around the spark plug. If you don't have that, it's okay. Just be careful. Maybe take a brush. You just don't want anything falling down into the cylinder when you open up the spark plug hold. These spark plugs are going to take a five-eighths socket. You want to get a spark plug socket. This is a regular five-eighths socket. If you put a spark plug in here, it's real, real loose, and you can turn it while you're trying to install it. The spark plug is going to fall out.
A spark plug specific socket has a rubber insert to grab on to the foursome part of the spark plug so when you put it in here, it seats. You can go to install it. It's not going to fall out and the same when you're using it to remove old spark plugs. You can lift them out of the engine and they won't fall down. We're going to use a three-eighths drive and my five-eighths spark plug socket. It should be on there.
Take my ratchet. You're going to remove it. These are only torqued to eleven foot-pounds, so it shouldn't take much effort to get them out. Once it starts to get loose, you can remove the ratchet. We just use our fingers to spin it out. As you remove it, the spark plug socket is going to hold it in place so if you need to move it around, you're not going to drop it.
So you can see this is our old spark plug and this is our new one from 1AAuto.com. Their threads are the same length. A single electrode. These are going to work great and give you nice performance on your vehicle.
Take our new spark plug and put it into our spark plug socket. Carefully place it into a spark plug opening. Sometimes if you go backwards, it helps you find the threads and then you can spin it forward to go in. It should go in very, very easily. If it feels like it's cross-threading, you should stop and make sure that it's going in nice and straight. Okay. Now that you've got it hand-tight, we're going to torque it to eleven foot-pounds.
The spark plug torque can reinstall our spark plug boot. Just push it on as hard as you can and just check that it's seated.

Okay, friends. Now, before we get started on this spark plug video, we want to go over a couple brief things. The number one concern is always safety. Make sure you're wearing hand protection and eye protection at all times. The next thing I wanna talk about involves the spark plug directly, and it's located right here. It's the gap between the electrodes. You wanna make sure you have a gap there, and the gap for this vehicle should be 0.040. You can get yourself one of these gap tools, maybe it'll come in handy. One thing about using a gapping tool is that it's made out of hard metal, and these spark plugs right here are made out of precious metals on the end by the electrode. If you shove this hard metal in there, you could potentially damage it. So maybe you could just put it up close, see if it looks like it's approximately right. And you could also compare it to the rest of the spark plugs and make sure they are all approximately the same going across. Once you've confirmed that they all look fine, let's continue with the install.
Now in this video, we're gonna be showing you how to do the front right spark plug, but the process will be the same for all. What we're gonna need to do is remove the lower part of the spark plug wire from the spark plug. You wanna be very careful that your engine is not hot because this is your exhaust manifold. Give it a nice twist, see if you can break it free. If you can, twist and pull, should come right off. I always like to take a peek to make sure that there's no damage, there's no moisture, and there's no corrosion. That looks like it still got some lubricant on there, so that looks great.
We're gonna take our 5/8 spark plug socket, and we're gonna come right down, put it onto the spark plug, gonna give it a little spin, you should feel a click in, go ahead and turn it to the left. I'm only gonna give it a couple turns and then we're gonna use some compressed air to make sure we blow out any debris that might be in there.
Let's just take a quick look at that spark plug. Look at the condition. Does it look as though it's got funny colors? Maybe it has buildup of any sort? If you see buildup, you know that you're not burning proper fuel and, of course, your new spark plug's probably going to get buildup over time as well. This one looks fairly decent and it's not worn at any angles. I don't see that there would be any issue. Let's go ahead and replace it.
So, we've got our old spark plug, let's grab our new one. And we're gonna look right along this edge right here. That's where it's gonna mate to the engine, you wanna try to compare those together. And then come right up along the top where the electrode is, make sure that it comes out to the approximate same length. If for some reason your new or old spark plug was higher or longer than the other, you know you're probably going to have an issue. More than likely you have the wrong spark plug.
Once you know you've got the correct spark plug and it's gapped as close as possible, let's go ahead and carefully install it into the engine. Just wanna find that hole, guide it in. Always start it in by hand, and you never ever wanna use an air gun for any reason doing spark plugs. We're gonna go ahead and torque down. When you torque it, if you're torquing it into an old head or a used head, you would torque it to 11 foot-pounds. If you're going into a brand new engine or a brand new head, torque it to 15 foot-pounds.
Now it's gonna be time to get your coil wire back on here. Before you do that, I just like to say, it's always a great idea to replace your spark plug wires when you're replacing your spark plugs. Either way, whether you're replacing them or not, I definitely recommend using some dielectric grease right along the area that's gonna go over the spark plug. That's gonna help this release easier next time. Go ahead and slide it on there. Make sure it clicks in. Beautiful. Follow the wire, make sure you didn't give any tugs and it's not going anywhere near the exhaust in any way. Do the same for all the rest.

You can move these heater hoses out of the way, just pull them out of the bracket and slide them to the side. Take the wire off the spark plug. You can twist it a little bit. It might help. And then try to pull it off. It's a good idea not to pull on the wire itself. Just try to pull on the base and you can slide this out of the way.
Before we take the spark plug out, just take a little compressed air and just blow around the plug. There may be some sand in there or dirt or debris, get that out of the way. And take a spark plug socket. It's a 5/8 spark plug socket. And you can use and an extension and take the spark plug out. And slide the old spark plug out.
Take the new spark plug. Put in the spark plug socket. And then gently, feed it over to where the hole is and just by hand, screw it in. And we can torque that to 11 foot-pounds.
You can always put a little bit of dielectric grease in there and then slide this over the spark plug. Make sure you lock it in place. And you do the same with the other ones. And move these heater hoses, put them back in the bracket.

Fit and looked like originals. I apparently have other reasons for the misfire code but this is only the second set of plugs in 268k miles so they were overdue anyway.
Purchased with ignition coils kit

Great value for the money. I had to readjust the gap of two plugs but overall they were set to specifications.
They perform as well as original.

After 20 years and only 92000 miles she was due for a tune up. Was glad I picked the TRQ brand spark plugs. After installing them and taking her for a test drive. I would definitely recommend these spark plug and would buy them again. My truck drives like she was new again

We do not have the pre-gapped specification available. We would suggest double checking the gap prior to install to ensure they were not affected during shipping.
