So I did a spark plug/cop change and I found these afterwards and not sure where they came from? Fuel rails the only thing I can think of? Well I guess one can't add pictures wtf lol?

Well anyways they are about an inch and a half round cylindrical blackish pins the looks like?

Never mind they are a part of the coil!!

 

They are boots for winter time!
Good luck.

 

What do they do? I thought it was just to prevent the coil from kinking too much?

A lot of people complain about this being a hard task, I thought it was super simple except the fact that I worked on a plug for an hour and a half trying to get the socket to catch with no luck. Yep turned out to be this stupid ceramic piece blocking the plug lol!!! Dumb dumb me lol
