I was under the impression that the factory plugs were the NGK's listed above, as that is what the dealer told me and that is what the parts program pulled up for a 2002 M54 325i (Automatic). Dumb question, but the M54 is the correct engine listing for this car, correct?
Anyway, I pulled the #2 plug out today and to my surprise, I read FGR7DQP and "Bosch" on the plug. I have looked for this Bosch plug, but I haven't been able to find it anywhere. As for the NGK's, the BMW part listing was for BKR6EQU with no P, and if I remember correctly, the P designation means Platinum. Maybe the program just didn't list it, as I didn't actually see the plugs.
I did a search and read a lot about spark plugs, and some people swearing by the Bosch +4's, and others with the Denso Iridiums, but I don't feel there is any gain to be had on a N/A car, especially one that is stock, with using a different plug. I drive VW's (R32 driver), and they hate you if you switch from the factory NGK plugs.
Also, to get to the last two spark plugs, I assume you have to remove the microfilter and its housing, otherwise I don't see how you would ever fit a spark plugs socket and the extension back there.
Did anyone else's car come with the Bosch plugs? I want a plug that is the factory spec, doesn't need gapping, and has the same temperature range as factory.
The car has just over 60k on it, and it runs fine, no sputtering or potential staling at idle, and the manual says it's ok for 100k, so I might not even need to change them. But since I have the cover off, and it is pretty straight forward (except for those last two), I may as well.
I appreciate all help,
