Has anyone purchased an Air Mass Meter from a bosch agent, there must be a cheaper option than the MB dealer without having to buy a poor quality spurious part?

Got a 1990 SL500 here in Kuwait, and as you may know, it is really hot here-mostly 110 + fahrenheit, and sometimes higher. Car runs hot most of the time--100-110 Centigrade. Coolant has been changed--what mixture do you recommend--40-60? How can I advance the timing? Not so familiar with this engine---has the dual distributors. Installed new plugs and distributor wires.
