Brought to you by 1AAuto.com, your source for quality replacement parts and the best service on the internet. Hi, I'm Don from 1A Auto, I hope this how to video helps you out and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show how to replace a spark plug on the 1998 Honda Civic with the 1.6 liter 4-cylinder engine and it's the same part and process on these vehicles from 1992 to 2000. The items you'll need for this is new spark plugs from 1AAuto.com, 5/8 inch spark plug socket and racket with an extension and a gap tool. Start off by disconnecting a spark plug wire and using a 5/8 inch spark plug socket, twist out that spark plug. If you're using a spark plug socket, the spark plug will come right up and out with the socket, otherwise you may need a magnet to pull it out.
SUp front is the old spark plug, behind it is the new one from 1A Auto, you can see that they're identical and they are going to mount exactly the same. Bring your new spark plug in, you want to make sure the gap's right so using a gap tool you want to pry that to the right size and for this vehicle it's supposed to be .044. Put the spark plug into the socket and lower down into place and just twist in and tighten it. In general, you want to torque spark plugs to about 20 to 25 per pounds. Once you have it tightened up then replace the wire and repeat for the other three.

Hi, I'm Don 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'll show you how to replace the spark plugs on this 2008 Dodge Caliber with a 2 liter engine. The items you'll need for this are new spark plugs for 1AAuto.com, a T30 Torx bit and ratchet, 5/8 inch spark plug socket, and a gap tool.
Located right here, are your four ignition coils, under each one is your spark plugs. If you want to start off, just disconnect this harness, push the tab and pull it off. Right here, there's a T30 torx bolt, just go ahead and remove that. Once the bolt's removed, the ignition coil pulls right out. Using a ratchet, an extension, and a 5/8 inch spark plug socket, just remove that spark plug, and it pulls right out. If you don't have a spark plug socket, it's just a 5/8 inch socket then you can just use a stick magnet to remove that spark plug.
On the left is the old one. On the right is a new spark plug from 1A Auto. You can see they're identical, and they'll mount and fit exactly the same. You want to use your gap tool to make sure the gap on the spark plug is right. You want just a little bit of resistance. For this vehicle we want .05, and it's right where it is. It's good to go. Now put the spark plug into the socket, and then lower it down into place and tighten that up. We're going to just fast forward as Don does this. Next, lower your ignition coil down into place and replace that T30 Torx bolt, and then, tighten that up. Then, you want to tighten these between 15 and 20 foot-pounds. and repeat the process for all of the spark plugs. Reconnect each harness and you're all set.

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 show you spark plug replacement. This is a 2003 Honda Civic with a 1.7-liter VTEC engine, and it's the same process for many vehicles with a 1.7-liter as well as a 3.5-liter. Items you'll need include new spark plugs from 1AAuto.com, flatblade screwdriver, 10mm socket, ratchet, or wrench, a 5/8 spark plug socket with a ratchet and extension.
Open the hood. Just pull the lever right here. Underneath, there's a safety latch, lift up. Lift it up and put the prop rod in place. Your ignition coils are located right on the top of the engine. Right here: one, two, three, and four.
Remove the top trim panel with a flat blade screwdriver. Remove the nut that holds the coil in place with a 10mm socket or a wrench. Lift it out. There's a tab on the harness connection, press down and pull and disconnect. Pull it up and out. And we'll do the same thing for the other three. Once you have the coils out, the plugs are right down inside.
Use a 5/8 inch spark plug socket with a ratchet and extension. The reason you want a spark plug socket is that once you twist it out, pull it up and out and the plug comes right with the socket. The socket has an insert that holds on to the plug. The spark plug socket is the best tool but if you didn't have one, you just had a regular 5/8, you would at least need a deep socket, and obviously when you unscrew it the plug is not going to come up with the socket, so you'll need a stick magnet put down in there to pull the spark plug up and out.
Use the spark plug gap tool and make sure you set the gap on the new plug to between 1 and 1.1mm. Once you have your gap checked, install it in. You can see the spark plug socket keeps it from falling down. Put it down in and very carefully start to spin it in. Make sure you don't cross-thread it. Once you get them in place, tighten them up. Use a torque wrench, 13 foot pounds. Then repeat the same thing for the other three.
I highly recommend a spark plug socket, but if you do have to use just a regular 5/8 socket, you want to be very careful not to cross-thread the spark plug. So use your magnet, put the plug down in there first, and then socket. Make sure you get the socket on to the spark plug, and then lightly turn it. If you feel too much force back it out, because you don't want to cross-thread the spark plug. As long as you're just lightly turning and it's not giving you any resistance, you can kind of look down in and it's centered in the hole.
Everything is good so you can then proceed the same way. Reinstall, push them down in. You'll want to just put the connector on them. It should go down. Then push them nice and firm, and then make sure your connect is clean. Put your four 10mm nuts back on and tighten them. You don't want to go too tight. Reinstall your cover. You're all set.
Thanks for tuning in. We hope this video helped you out. Next time you need parts for your car, please visit 1AAuto.com. Also check out our other helpful how-to and diagnosis videos.

Good quality.
Quality parts
Quality parts at a great price and really fast delivery!
Perfect fit. Operates great.
Massive improvement. They work great.
Anybody who works on cars will tell you when you find parts that work right the first time and also last a good amount of time, you stick with them. TRQ, for me, is relatively new to the market. With my first purchase of a TRQ part (Window motor) I found it to be spot on, as far as, holes lining up. Also, the motor performed better than others I had previously bought to fix the same problem. Now for these spark plugs...I recently put them in and they work as expected, but I did my research as to which type of spark plug to get for my car. If you do your homework, you should have no problems picking the correct spark plug for your car. As for TRQ, I haven't had any regrets buying their parts (knock on wood) as long as they keep putting out quality parts I will keep buying them for my car repairs. When they drop the ball I will stop buying / recommending their brand to other people.
Great quality, was surprised after how the engine ran after installation
Turned my car into a speed demon, and sounds wonderful.
Great part with fast shipping
