I too am debating whether to use Bosch double platinum or NGK iridium. NGK states that the iridium is for the turbo.
I’ve read both sides, that the iridiums will last longer, and that the double platinums will last longer because it has a thicker wire than the iridium. I’ve also read that the NGK laser iridiums are not the best iridium.
So, I’m open to educated comments.
Going into a 2012 X3 35xdrive (turbo).
Thanks.
