what kind of spark plugs are you guys using? I replace my e46 with NGK iridium but want to try the NGK copper for the Z3.

I'm using bosch platinum +4 on my 00' M Coupe, replaced every year. Haven't tried NGK yet though

when I was changing the spark plug on the e46, I saw that the car came with NGK plugs. I havent open the Z3 yet, but what kind of plugs do they use originally borsh or NGK?

They use oem bosch on mine.. It should be the same for your Z3 unless they replaced it already with aftermarket.
