whats so bad about putting platinum plugs in?.... >_>;

 

They damage the ignition system.

The problem is that the Bosch platinum plugs (like many other brands) actually have a minute center electrode surrounded by a ceramic insulator. (Have a look, only the tiny silver center portion is the conductive platinum) Saturn "S" series fire their plugs TWICE each four stroke cycle, once at the compression stroke, and once at the exhaust (waste spark) When it fires in the exhaust stroke, it fires "backwards" requiring that tiny center electrode to recieve spark instead of emitting it. It''s not up to the task, and misfires.Edited by: Low Saturn

 

Well, thanks for that info. I was about to invest in some for my saturn because they worked wonders when i put them on my moms ford aerostar. good thing i didnt.......
