Okay. I feel like a total newbie considering i'm asking how to change my spark plugs. I pulled the boot on both sides of the valve cover and I tried a 15mm and even a 5/8" deep socket with a extension and couldn't reach the spark plug!

It seems the hole is too narrow. Do I need to pull the valve cover to swap the spark plug? Also, where are the other two spark plugs (I believe the twin sparks have four??)

Any help is appreciated.

Thanks.
