What do you think about my spark plugs??
How bad are my spark plugs??
I just changed the spark plugs on my 08 335i, the car didnt have any misfire codes or any major rpm swings. from time to time i can feel a small misfire at idle. from time to time also i see the rpm needle travel between 550 and 650 at idle. These are "bmw bosh" plugs so i assume the plugs that the car came with from the factory. the car has 30k miles and didnt have any spark plugs change on its service history from the previous owner.
these are plugs 1 to 6 from right to left.
do you feel a change in performance with fresh spark plugs (i am FBO)?
