what the heck
I am 60 years old and have worked on cars my whole life, but I have never seen one of these. It is some kind of spark plug extension. I cannot think of a purpose other than to decrease performance and drive ability in every way. Does anyone know what and why it exists? I am removing them and installing the plugs directly.
