Replacing spark plugs

I am new to the forum. I am attempting to replace my spark plugs. I have a 2004 BMW 330ci and when I removed the trim cover I found that I do not have ignition coils with harness plug clips. Instead these ignition coils have wires running directly into them.

I believe these are incap ignition coils.

I have tried to find instructions on Internet without any luck.

Can someone provide any guidance on how I can remove these ignition coils?

Thanks in advance for any help.

Lift the little plastic tab to release the plug. When you lift the plastic tab upwards the plug will slide out. Remove the plug, then pull the coil up, twisting it a bit (does not move a lot)

thanks paraklas! I fiddled around with the plastic tab and couldn't figure out how to lift it... the plastic is a bit brittle and i was worried about forcing it...did not want to end up with a broken ignition coil....could you describe specifically how i lift the plastic tab?

Thanks!

The housing plug should lift as the arrow. It is pivoted so one side only will actually lift. at around 45-50 degrees it will pop the plug out
