Just brought an induction kit for my astra and some bigger hoses to joint to throttle body but need a ally joiner pipe with the hole for the MAF sensor.

mines one that pushes in to a hole not an inline one.

Does it have to be a particular pipe or any universal one that i can drill a hole into for it to fit??????

engine is X16xe/ x16xel either one but not sure.

Also whats the black box for just above the rocker cover and throttle body joint to the air intake pipe???? can this be removed?????
