Re: EF Airbox
Ahh yeah, i see where you mean now.
I think youve probably only got 2 options apart from BA piping - one being EL (as its the same shape as the AU one, but i dont know if its wider or not), or getting a steel one made up.
I would be inclined to give the EL intake pipe a go, i'm sure someone on here actually had their car dynoed, once with EF piping, once with EL, and the EL did make a difference.
But yeah, I don't know for sure if the AU piping is bigger than or the same diameter as the EL piping.
