Yepp there was some problem with fouling as well. Dont fix what is not broken.....: Is your car running ok? Maybe even better with these plugs? Then stay with the 6ES. The best way to determine what plugs to use (or if there is a need to change heatrange) is to look at the plugs. A viual examination of the plugs will tell you a lot about your engine.....Have a look at the NGK site for info on how to "read" your plugs. If the plugs look ok, dont change them. If they show signs of running hot or cold, change to the appriopriate heat range. Your driving style will determine what is best in your car. ok? /M Jeff Augenstein wrote: > Since this thread has turned into one about spark plugs I had a question > along those lines. > > At my 65k mileage major service my Saab dealer replaced the NGK BCPR7ES > plugs in my 94 Aero with the NGK BCPR6ES plugs.
