Hi,
New here and my tag is my cars not a keyboard mash.
Just got a stock FGX G6ET with 45k km, ex Ford exec, August 2015 car, and was going to change the plugs. Where the intake piping goes over the rocker cover, there is a rubber isolator hex shaped thingo that just turns if you try to undo the torx bolt. Any help on what that one is? Left it so I don't I <3 Bananas it. Sorry if this has been covered before, I have tried to search the forum, but to no avail.
Thanks, Shaun
