which spark plugs to get ?

I have a 2005 E46 318CI with the N46B20 engine.

I'm getting some parts on mister-auto.ie but I'm confused about the spark plugs

when I put in my reg number, it give me a few different types of spark plugs that it says will fit. There are some serious differences in the prices though.

The Bolk ones are very cheap, are they any good ?

from my research this page says that I need:

IZFR6H11 - NGK Iridium Spark Plug (4294)
http://sparkpluglist.blogspot.ie/2012/07/bmw-spark-plug-reference-guide.html

seems like overkill ????? I'm only saying that because the NGK website says that these ones are for "performance engines" and the fact that this ones don't come up on mister-autos list

Go for ngk platinum or bosch platinum iv found local motor factors usually match misterautos price on plugs if you want them today

then i see ones with different amounts of poles etc... does that matter?

Laser Platinum ngk are the recommemded plug should be 4 prong roughly 10e per plug

mister auto reccomends these ones:

that right ?

sorry I'm asking so many question but I'm new to the world of cars. If any of you ever need any techie help with you PCs, Laptops or phones then i'd be happy to help if i could

Yep thats them

NGK are better than Bosch by all accounts, both were used by BMWs as OEM suppliers now & in the past. Also check the dealer price for OEM branded plugs, I noticed that the dealer was the same price as the motor factors for my e63 630i.
