you do NO modification to the ballast, you just relocate it in order to make room for the intake tube. in my for sale ad you can see that you can use the e46 m3 ballast cover.cb's/328ci said:Great, Thanks!
Does the OEM wiring work for the ballast or does it need to be extended?
Can the OEM "snorkle" be removed? ( goes from airbox to grille )
Anyone have anything else to add?
yes the snorkle can be removed. sorry, mine is sold. 323/325/328 all use the same coupler.
