Do these look OK?
I haven't been reading spark-plugs since my dirt bike racing days. On my bike, those would have indicated a slight lean condition. (IMG:style_emoticons/default/idea.gif) What about a 993 3.6L motor? Still too lean? Or OK? (IMG:style_emoticons/default/confused24.gif) Andy Attached image(s) |

............OK everybody.......You think the flash from the camera is making the SPARK PLUGS look to "white"....this is possable... SO lets ask andy to rephotograph the spark plugs in a more normal lighting condition.....One other thought, the multiple ground spark plugs, will restrict FLAME propogation in the combustion chamber. I,m thinking these are not factory recommended spark plugs......and generally you (it,s possable to tell)....can tell if the heat range and spark plug temperature is correct by reading the spark plug threads....Andys plugs show no color change from top to bottom....possably due to the photograph and lighting.................just a few thoughts..........................murray.

I,m thinking these are not factory recommended spark plugs...... Stock 993 spark plugs (Beru). That's the way they come from the Factory. I replaced them all with a set of the same. I think i'll look around for someone with a sniffer and maybe even some software to plug into the OBD1 port ... (IMG:style_emoticons/default/idea.gif) Andy |
