I'm almost done with my M50 swap in my E30.
Just some questions remain..
- As you see on the pictures, what's up with the red number 1, where does this one needs to go too? or can it be removed? is it fitted correctly to the throttle body?
- the red number 2 where does that one go? (it's also the yellow one in the other picture)
- the green number 2 what's up with this one?
- finally, the blue one is good like it is, this can be ignored??
or am I missing something out ?


thanks alot.
