So, I have a 2007 bmw 335i sport. Should I purchase the mosfets that this site takes me to or do I need a different type?

Those worked for me. Also '07 335. Change them all though since they're real cheap. Apply new solder to loosen up the old ones and they'll pop right off.

Instead of making a new post I figured I'd ask here to clarify.

I got a 30BA, verified a bad mosfet and I'm making the change to MSD81 from 80, to be sure I should swap out the injectors and ignition coils at the same time? (I have the BL Coil setup)

This might be unrelated but I also got a 2C3B Lambda probe in front of catalytic converter, not plugged in.

I don't think I would change them out unless they are older or failing. Just to the Mosfets and test.
