I would go with bosch platinum. Some people like the NGK.

NGK is a good choice...What are you after? Platinum plugs have more resistance than cheapo copper core...if you are after raw performance and don't mind changing them frequently... copper core is the way to go. If you hate changing plugs and want something that will last a long time..go with platinum. You would probably only notice the difference on a dyno...so in a way i am splitting hairs, because academia rocks!

I just remembered I don't have any hair left to split...Boo Hoo

many people have said that copper spark plugs are better for bmw's and their aluminum heads, also many have reported bogging and other issues with bosch platinums, i noticed a rough idle during cold start ups when i switch to bosch platinum 4's, when i get a chance i'll be buying oem ngk's

i recommend getting oem ngk's the first time around

ive heard oem bosch plugs are the way to go

I had both Iridiums and your basic copper cores. Couldn't tell the difference. Not even gas mileage changed.

hey, platnium plugs are x4 the price and last x2 the time of normal ones. so not really worth it in that perspective. i got ngk's and they're just fine, just make sure you get the double headed ones, not sure of the proper name.

by stock plugs. bmw ignitions are unique. platinum or iridium plugs are pointless when used w/ stock BMW ignition.

The only issue for me with buying stock plugs is that the dealer charges $13 per plug for the bosch coppers and I can go out and buy iridiums for less than $10 per plug. If performance is comparable then why wouldn't I get NGK iridiums?
