Spark Plugs Question

[bullmand]

After a very bad experience with aftermarket plugs, I'll be sticking with the factory recommended plug. There are four part numbers for the M44.
First:
BOSCH F 7 LDCR
NGK BKR 6 EK

Then this happened:
TIS SI 12 05 98 (368)
Apparently this involved some sort of change to the recommended plug. I've never seen the actual bulletin, but I think it had something to do with the rough idle. So, now we have new parts listed as high power:

BOSCH FGR7DQP
NGK BKR6EQUP

If anyone has more isight into the difference between the originals and the high powers, I'd love to know what it's all about.
Thanks.

Guy,
I'm not sure about the NGKs, but all the Bosch plugs come with the correct gap or they don't need to be gapped.

The high power plugs when i replaced mine where the same spec as used in the V8 M5........sort I bought a set for that vehicle and it worked out a bit cheaper than two sets for the M44.........fine by me!

Both makes of plugs are set, and should not be gapped...unless you drop one on th garage floor and f**k it up!
