one thing i gotta say i went to the stealer
and saw the Bosch replacement plugs for the car.
wanted 31 bucks.
they are Bosch and i dont like that the center electrode is the size of
seems anything gets on that and u have a problem.
but those are what BMW puts in there.
im glad i get the NGK years ago but i must
say i never remembeer the originals on my 328i looking like these Bosch
Regular spark plugs vs platinum
The plug with small center electrode is platinum.
Some people have stromg opinions about the brand, and regular vs platinum.
My only advice is use an OEM plug that's recommended by BMW. I've used NGK and Bosch. I've used regular and platinum. But they were all OEM parts and they all ran well on my 325.
You'll have to decide if the platinum's longer life is useful, or worth the extra cost.
