"Hi, I'm John, with expertvillage.com. We're changing spark plugs. Now, we have the spark plug wire removed. From the distance from here to here, that's how far you need to go down, so get an extension for your ratchet and your socket that's long enough. Then when the spark plug is sitting just like this, straight up and down, and this spark plug wire hooks right onto that, so it's sitting here just like this. Now, this is made from metal and porcelain. You don't want to break the porcelain. There's going to be porcelain shavings all over your engine. You're going to have to take it apart and clean it. Don't do that. Be careful. Now we have the exact size, because if you strip this you can't get it out, so make sure you have the right size. Get your new one and test it, and once you do this the first time you'll know your car. So, we want to go straight down and righty-tighty, lefty-loosey; be really careful. If it's stuck where it won't move, then just be very cautious and careful cause' you don't want to break this. So now, let's take it out."
