Which spark plug wire should I get for my 1992 300ce. 121000miles, M104 engine. I would love to enhance the power a little bit, so what would be the best set up, so far the spark plugs recommended are Bosh Super H9DC. My car is beyond slow, so a little more power when I change all the parts will help greatly.

Also is it possible to turbo charge the this car. I am afraid that the turbo might crack the block or in the end I would have to completely replace everything except the block. Which I might do in the long run.
Well over all I am confusing about what to do with the car, all I know is that I want to enhance the power.
