So I scrounged the old interweb to find the easiest way to replace the spark plugs on my 2008 JK in particular the one by the passenger side firewall. I found that using the 5/8 spark plug socket along w the 3/4 socket and a short extension was all that was needed to get that badboy out. I also sprayed the plugs w WD40 the day prior just to make it a bit easier to work with.

I read and watched videos that recommended taking out the the battery tray, removing the front fender o just taking it to the dealership.

The way I did it was so much easier and cut all of that fender removal shenanigans from the picture and saved some time. Hope it helps

 

So you came in at it from the top? I cheated and pulled the fender flare and liner out. You can look directly at the plug.

 

Yup, I knocked it out going at it from the top. It was very easy to do so as well. I used a rubber vacuum line attached to then of the plug to get the plug back into each hole initially to avoid cross threading as well. Then finished off w the plug socket.

I'm not to familiar w taking fenders off. Seemed too time consuming for me. But if it works it works. I just wanted to put another tool in everyone's toolbox.
