I have a 06 M35 Sport and I'm possibly going to change out the spark plugs. First of all I wanted to ask what type spark plug would be best for performance and is there a specific torque setting when putting in the new spark plugs? Also, I wanted to find out some general info on the spark plug wires. I'm having a little difficulty finding new ones and wanted to ask which ones you would recommend and where to find them?
Thanks
