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.

Work great
Just what I needed!
Received it in a timely manner and got the exact part needed the first time
Everything perfect
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
Easy fix and great parts
Performs as well as factory original plugs. A good mantiance replacement part for my '04 Chevrolet silverado 5.3 with 206000 showing on the odometer. Have used several TRQ parts with no issues.
Great value for the money. I had to readjust the gap of two plugs but overall they were set to specifications.
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.
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.
Thank you for your inquiry! Can you provide us with your vehicle's year make and model?
Yes, these should be pre gapped.
Yes, these will come as being pregapped.
