Coil pack is a coil pack is a coil pack???

2004 745li 115k miles, I am replacing valve gasket, I think I read somewhere here on the forum that you need to keep coil packs in the same order you took them out and put back into the same spot,,,they all look the same to me.....any help would be appreciated,


P.S. i ordered new spark plug tubes they look like gasket is attached, do these come off and can you buy just the gasket....????



Thanks ahead

I don't see why the order would matter. I didn't put mine back in order

Order doesn't matter.
Spark plug tube is a whole piece to replace.
