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're going to show you how to replace a spark plug on this 2004 Volkswagen Jetta with the 1.8T engine. The items you'll need for this are new spark plugs from 1AAuto.com, a Phillips screwdriver, a flat-blade screwdriver, a gap tool, a 5/8 inch spark plug socket and ratchet, and for spark plugs three and four, you're going to need a 10 millilmeter socket, and for four, you're going to need a 5 millimeter Allen bit.
First, we have to remove the engine cover by loosening these four Phillips clips. Just loosen it while pulling up on the engine cover. Then, the engine cover pulls off, and you can set it aside.
To access spark plugs one and two, you just push on the tab on the harness on your ignition coil and pull the harness free. Then, pry up the ignition coil, and your spark plug is down there. We're going to show you on a harder one the full process. For this, we'll just put the ignition coil back and reconnect the harness.
For three and four, you're going to first have to remove this 10 millimeter nut, right here. Then pull this small air box off and set it aside. You can now access three, and it's the same process as one and two. To get to the fourth one, you have to remove these three 5 millimeter Allen bolts. We'll just fast-forward as Don removes those. Pull the bracket off and set it aside. Then, just like before, push on the tab and pull the harness free. You may need to pry it to separate it. Then just pry the ignition coil up and out.
Using a 5/8-inch spark plug socket and a ratchet, you just want to loosen up and remove the spark plug, and it pulls right out.
On the left is the old spark plug. On the right is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same. You should always check to make sure the gap is right using a gap tool. You want it to be .028, and you want it to have just a little bit of resistance on the gap tool. If it doesn't, push the tab in or pry it out a little bit so that it does. Then put it into your spark plug socket, lower it down into the cylinder, and tighten it up.
Push your ignition coil back down into place and reconnect the harness. We'll fast forward as Don tightens those up. Now replace that small air box and the 10 millimeter nut that holds it into place, and just tighten that up. Line up the four Phillips clips with these four holes. Just push the engine cover down into place and tighten up those four clips. You're all set.
