Hello. I watched some videos to see if it was doable for me, ordered the NKG spark plugs, bought the 14 mm 12 point deep socket, the extension and the torque wrench, everything was set to a easy adventure, removed the cover, removed the coil, and attempted to take put the first spark plug, and to my surprise nothing came out, so I started to investigate and it seems that the tube where the spark plug is sitting on gets narrower down there and my socket can't reach the spark plug, is that right? Did I get the worng socket? I tested the socket on the new plugs and it fits perfectly, but it just can't reach it, this is the socket I got.
