How to change the spark plug

How do you change the spark plugs on a 2004 tacoma 3.4L? Is there anything special you have to do?

The passanger side is really pretty easy. You simply need to remove the intake tube to gain access to the coil packs. You need to remove each of the coil packs one at a time and use a long extension to reach the plugs.

The drivers side a little more of a headache as you're dealing with more stuff. The front two plugs are pretty easy as you can get past the intake to get the socket in the hole. The last plug required me to remove the intake brace to get the socket and extension in there. You also need the extra room to allow you get your hand in there to remove the boot.

Speaking of the boots. If yours are stuck like mine were you'll want to use a flat screw driver to GENTLY lift up the rubber edge of the boot and spray a little WD40 under there. Let it sit for a couple of minutes and you should be able to pull the boot off.

My plugs came out after 140K miles without any kind of issue so don't worry too much about that.

I do recommend using Anti-Seize on the new plugs just don't get it near the tips.

While you're doing all this you might as well check the bolts holding the valve covers down. All of mine were loose (like finger loose) and leaking. After tightening they no longer leak.

On the passanger side. Now is a good time to check and clean the throttle body and mass air meter as well.

opening a 5 year old post and using the wrong video is not a great way to build your post count
