I would like to replace spark plugs on my 95 s500. It's got 87kmis on it but plugs are seem to never been replaced by previous owner. I opened up the black cover tried to pull red ruber plug head things but wasn't able to . It just turned side to side so couldn't go any further. I appreciate any advice.

Thanks a million in advance, johny
