5.4L 3v Spark Plug Removal Instructions

Well I finally had one come in the shop recently after not seeing them for a long time. So I decided to shoot a video on the current favorite removal method that is working for us shops out there, since there are a few videos out there but they are all of poor quality. This works about 90% of the time. It seems you will usually break one out of 8 though and for that I have a new video coming out showing in detail the extraction process made simple. I hope this helps as this can be very costly. Most shops charge a half and hour more in additional labor each plug that breaks this can really add up!

I pretty much never break any of the plugs anymore when removing. The process is pretty simple. Get the engine as hot as you can get it. I mean full temp. Shut down the engine and quickly remove 2 coil packs. Use an electric impact and quickly burp in reverse and then forward. I do this 2-3 times. Then full out. Hardly any break using this method.
Sorry, but I wouldn't think of using an impact gun on a spark plug.

I'll take the slow sure way.

You just have to be smarter than the electric impact. Short burst just to break the carbon bond loose. Out of many, many, many 5.4L 3V spark plugs I had to remove, this method is almost 100% effective. The chemicals just don't seem to work. Even sitting overnight.
