Spark plugs too tight, a quick tip to help loosen.

[0:01]Sometimes a spark plug can be quite difficult to remove and it could be that the plugs have been in the engine a long while or it's the first time that they've been removed since the vehicle was delivered new. But what I do if they're tight is I just use a small amount of free all and then gradually work that plug backwards and forwards until it starts to loosen up. Sometimes you will hear a creaky noise, but as it becomes loose, it's then safer to remove that spark plug without risk of damage to the thread, because if that happens, it's going to be quite a costly repair.
