Hi all, just wanted to intro myself as a new member. I am fortunate to run a 2004 CL55K AMG. And although I'm reasonable at most DIY car mechanics I'm a little hesitant to change all 16 plugs without some advice, please. Do I need any special tools etc to remove the plug leads? I understand I have to remove the engine cover and the individual coil packs but not sure about the space in removing the lead/plug - it looks very tight! Also not sure what make of plugs, I've been advised to use Bosch? Any help/advice would be greatly appreciated. Thanks in advance, Matt.
