What is the correct torque on these?

Sorry I don't know, but like with any spark plug, just snug them down. They aren't going anywhere

Are these plugs pre gaped?

You must always check the gap on spark plug replacements against recommended gap for that specific plug. Even plugs that are pre-gapped can have discrepancies due to shipping and handling. - worked at a auto parts store for years

Will this fit perfect in my 2012 c250 coupe?

Not sure but it fit perfectly in my s550 benz.

Do i have to game these? what to gap with? and what size socket is required?

You do not have to gap them. It is a 5/8 deep socket.
