Hi there,
I would just like to know if these spare shops' info is correct?
When i recently got my M3 it had all its oil services on time, but the rest was way overdue.
When the car was on working temp and idled, it had a slight misfire now and then, but the moment it was above 1500rpm it was smooth all the way to red line. When cold it was also smooth
When I serviced it myself, I saw that the owner’s manual stated the car uses Bosch Y5DDC spark plugs and that was the same ones in the car at that moment.
However, when I went to buy new plugs all the spare shops’ guides stated that the S50b30 used the NGK Platinum DCPR8EVX.
Now that these are fitted, the car still does this slight misfire on idle, but far less than before.
The car is now definitely stronger than before and I think it performs quite well. It can stay with my one friend’s 4dr 3.2 M3 and can drill a 5.7L Lumina SS.
Now to get to the question:
Is the car only better with the new plugs only because the previous ones were in such a bad state but can even still be improved upon?
Are these DCPR8EVX ones the right ones or will it be better with the Y5DDC?
Where does one get these bosch plugs in PTA?
Can it be something else that causes the mis on idle?
Thanks,
