Which Spark plugs to use

I think it's time to change my spark plugs but which ones would be best to use

Spark Plug - Bosch ZR5TPP3
or
Spark Plug - OEM BMW

I'm not a fan of bosch, but there doesn't seem to be much else we can use on your beemer. When ever i used bosch spark plugs in my previous e46 it ran horrible compared to when i used NGK spark plugs

While i'm at it which oil would be better to use

Castrol Syntec European Formula SAE 0W-30 ( which is almost impossible to find in canada)

Mobil 1 SAE 0W-40

Liqui Moly 5W-30

Hi,
i am the tech manager at Autolite spark plugs. I recommend using our XP Iridium spark plugs, your car will run great with them. I am willing to send you a set for free (they retail at 7.29 each) if you will post your results in this forum. I am very confident you will love these plugs.

What results would he post? O-60 time? MPG? Emissions? Seat-of-the-pants opinion?

What could a regular owner of a BMW (without access to special test equipment) measure to determine the Autolite plugs make his car run better than the OEM plugs?

Must be Arnold's markup! That's a BS price for the plugs. Someone is blowing smoke!! Tischer sells them for $18.20 ea.

Yes, Bosch plugs work just fine. Just installed them on my son's e90. Just torque them to specs (23 Nm if I remember right) and when you put the microfilter back- make sure it is seated and sealed well. Also, make sure the coil on top is put back correctly.

Proud to announce that motorking is a real, live person that came through. I just received the XP Iridium plugs today, and they look very well built. I will install them this weekend and post my results. I have 73xxx miles currently on stock plugs. For now here are some photos.

We will be releasing a plug for the N54 in 2012. Had to wait till the volume warranted production.
