yes, both are correct!:thumbup:NGK BKR6EQUP.....i think thats it and BOSCH FGR7DQP
I was looking for the right plug for my 2002 525i which didn't seem to be on that (old) spark plug chart posted prior.
Here's what seems like a better chart (for all BMWs) I found in my travails.
Even though this post was made in 2008, the chart lists E39 525i plugs as:
- non-adjustable NGK BKR6EQUP or Bosch FGR7DQP
Does that seem right to you?

For the record, MatWiz posted a nice 3-page BMW TIS on BMW High Power Spark Plugs over in this post ...
For the record, this thread acted as a self-serve reference today, over here:
- E39 (1997 - 2003) > OE Spark Plugs - NGK Vs Bosch
- BMW spark plug application charts (1) (2) & the best plug to use (1) (2) & a deciphering key (1) & keys to reading plugs (1) & the truth about torque & anti-seize (1) & the truth about gap (1) (2) & DIYs for replacing spark plugs (1) (2) (3) (4) (5) (6)
- E39 (1997 - 2003) > OE Spark Plugs - NGK Vs Bosch
For all to benefit, here's what's currently in the bestlinks for spark plugs:I just pulled the plugs out of 107k mile 2002 540iA sport. They are Bosch and say BMW on them. I believe them to be original based on condition and label.
I've read a lot of the thread on here from Bluebee's links and searches which say the NGK are original. Did they change at some point during the model run?
...
Edit - re-read one of Bluebee's links and found the answer.

I missed that tab in all my other reading.
They're both OE.

For the record, here's one poster today who is very unhappy with single-pronged plugs ...
- E39 (1997 - 2003) > NGK sp plugs: 2-prong vs 4-prong?
- E39 (1997 - 2003) > NGK sp plugs: 2-prong vs 4-prong?
Pay attention to this! Do not play around with substituting 1 or 2 pronged for 4 pronged! I got a full service from a non BMW garage 8 months ago. After I got the car back the motor had these flat spots and I had to be very sensitive on the gas. Soon after, I lost one cylinder and took it back to the garage. The guy told me it was the ignition coils and I replaced all 4 for 500 bucks.
The other day, after months of frustration and temporarily losing a cylinder again, I took the car to the BMW service place. They told me that there were 1 pronged plugs installed rather than the 4 pronged. 270 bucks later the car runs SOOO sweetly that I can't even describe it to you. Do not mess around with components on these cars. They are precision instruments. It might seem like your car is running fine, depending on the model but I wouldn't be surprised if there was some effect on gas consumption.
I would like to add Mike's Miller thoughts about spark plugs. Might shed some light about all those problems with the Bosch spark plugs.
"Original BMW Bosch Spark Plugs vs. Aftermarket Bosch Spark Plugs
Like just about everything else on the modern BMWs, Bosch spark plug choice is complicated and confusing. The short answer is if you order the spark plugs from BMW (usually there is a choice between Bosch or NGK), then you are good to go and there is no confusion. But they are expensive. Savvy enthusiasts have found that Bosch has a part number for commercially-available spark plugs that cross-references to the BMW original equipment Bosch spark plugs, often at a fraction of the price. The problem is, the commercially-available (aftermarket) Bosch spark plugs ARE NOT the same as the original BMW Bosch plugs even though they cross-reference and they do work. Dealership technicians report problems with the commercially-available Bosch Platinum +4 spark plugs in BMW engines. I have never seen this personally, but physical inspection does reveal differences between the original BMW Bosch spark plugs for the modern cars and the commercially-available Bosch Platinum +4. I use the factory plugs in my E46. Now, when we're talking about older BMWs, where the original BMW specified spark plugs are Bosch copper or silver plugs, everything is completely different. On those cars, there is absolutely no difference between the original BMW spark plugs and commercially-available Bosch cooper or silver plugs. I realize this requires a certain intimate knowledge of Bosch spark plugs, and I don't know what to tell you about that except to ask if you don't know, or just buy them from the dealer."

Is this another reason to go with the NGKs instead of Bosch?... the commercially-available (aftermarket) Bosch spark plugs ARE NOT the same as the original BMW Bosch plugs even though they cross-reference and they do work.
Is this the backing-out-over-time issue?Dealership technicians report problems with the commercially-available Bosch Platinum +4 spark plugs in BMW engines.
I'm sure the cutoff date between 'older' and newer is inherent in the chart above - but - if anyone knows it offhand, it would be nice to list the year where the changeover matters.when we're talking about older BMWs... there is absolutely no difference between the original BMW spark plugs and commercially-available Bosch cooper or silver plugs
For example:
- Bosch plugs for E39's built up to & including [insert year here] are exactly the same between dealer & aftermarket
- Bosch plugs for E39's built after [insert year here] are slightly different between dealer & aftermarket
