I tend to agree with you. I have been using the Bosch +4 plugs in my 87 9000S. Yes, mine is a non-DI Saab, I have read comments by other DI-equipped non-turbo owners, who have tried the Bosch + 4 plugs with success. But there are those diehard NGK users who think it is impossible for Bosch to duplicate the same resistance used on one their plugs that NGK uses. In fact I have used Bosch Platinum plugs in all of my Saabs, 83 900T, 87 900S 16V and 87 9000S 16V. Ken Washington TGhosh wrote: > Hi, > > Why is everyone so adamant about using ONLY NGK in Saabs?
