If your sig is correct and you have a 2005 530 or 525 you do, in fact, have an M54 engine - same as me.
Granted you should always try to check the gap, but it's nearly impossible on the Bosch Platinum +4's they have the 4 prongs on them and there really is no way, short of destroying them, to check the gap. They tell you the gap is preset from the factory.
Also, keep in mind that with Platinum and iridium plugs you need the special tool to check the gap, the old blade type can easily damage the core and ruin your plugs.

My Ride: 2006 530xi (Titanium Grey/ Black interior) Debaged, L.e.d. light upgrade throughout. ACS roof spoiler. H&R sport sprigs, Angel eye upgrade, euro sticker, ,matte black grills.
I just ordered 6 NGK Laser Iridium ( ILZFR6D11) off of eBay for $69.99 I dis research and think the Ngk's are best for the car right now. Plus Ive used them on prior cars and theyve been great.

I replaced recently with OE NGK platinums. The bmw OE plugs can be either the NGK or the Bosch they both made OE plugs and both these plugs are very good. They sell for about $15-$20 here in Canada, so I had a fellow member who was nice enough to buy them from autozone in the US for $4.50 a plug and ship them to me. I installed them myself which is also quite simple.
How do I check the gap. Which type of Spark plugs should i go for?

I'm confused too. I notice some plugs have 4 prongs and some don't. Assuming I go to realoem.com and check for part number with the last 7 digits of my VIN, would this be the correct plugs? Also, I thought NGK plugs come pre-gap so if the gap is not correct, how do I adjust it?
Thanks guys.
